Answer:
4. the answer is 20
5. x=12 y=30
6. MLV = TUV bySSS
7. ABC=HGF by SSS
to show work:
4. 15/12=25/x (cross multiply)
=15x=300 (divide both sides by 15)
= x=20
5. the triangle is equilatieral so all the angles are the same. this means 60=2y.
if you isolate the variable and divide both sides by 2, you get y=30
6. 49/14 = 28/8 ?
if you solve both the division problems, they both equal 3.5, meaning the side lengths are the same so the rule would be SSS or side side side
and you do the same thing with the next triangle too
hope this helps!! also brainliest would be nice but you dont have to

Checking for a perfect cube :
3.1 3m3 + 5m2 - 5m + 1 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 3m3 + 5m2 - 5m + 1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -5m + 1
Group 2: 5m2 + 3m3
Pull out from each group separately :
Group 1: (-5m + 1) • (1) = (5m - 1) • (-1)
Group 2: (3m + 5) • (m2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Polynomial Roots Calculator :
3.3 Find roots (zeroes) of : F(m) = 3m3 + 5m2 - 5m + 1
Polynomial Roots Calculator is a set of methods aimed at finding values of m for which F(m)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers m which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,3
of the Trailing Constant : 1
Let us test ....
P Q P/Q F(P/Q) Divisor

-1 3 -0.33 3.11
1 1 1.00 4.00
1 3 0.33 0.00 3m - 1
The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms
In our case this means that
3m3 + 5m2 - 5m + 1
can be divided with 3m - 1

what is responsible for the blue sky
Answer:
I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."
Answer:
the blue sky is caused by sunlight reaching earth atmosphere which is scattered by the gases and air particles. which blue light is scattered more so that is why the sky is blue

If cm= (K2-15) in cm = (10k +9) in how many inches is cc
Answer:
Step-by-step explanation:
cm= (K2-15) in cm = (10k +9) in
K2 - 15 = 10k + 9
K2 - 10k = 9 + 15
K2 - 10k = 24
2k - 10k = 24
-8k = 24
k = - 3
use the product property of exponents to justify that (9^1/2)^2=9
The rule states that
[tex](a^b)^c = a^{bc}[/tex]
So, in your case, you have
[tex](9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9[/tex]

Answer:
Step-by-step explanation:
This is a difference of squares.
√x^2 - √49 is the basic formula for factoring a difference of squares. The idea is that the middle term has been cancelled out.
√x^2 = x
√49 = 7
(x - 7)(x + 7) is the way this factors.
(x - 7)(x + 7)
===========
(x + 7)
The (x +7) in the numerator cancels with the (x + 7) in the denominator.
The answer is (x - 7)
====================================================
She might have wanted you to do it like this.
(x + 7) || x^2 + 0x - 49 || x - 7
x^2 + 7x ........... Subtract
==========
-7x - 49
-7x - 49 ...... Subtract.
=============
0
Or she might have seen you do this
x^2 - 49 x^2 49
======= = === - =====
x + 7 x 7

Frankie was thinking about her mother cutting up the
lasagna when she noticed a very useful connection.
She recognized that any fraction in which the
numerator and denominator are the same is equivalent
to 1. In addition, multiplying a number by 1 leaves that
number unchanged.
"WOW," she said, “I can use this idea to find a whole
bunch of equivalent fractions!” She showed her team
the work below. “Look!" she said, “It's the same as
using a GIANT ONE!”
Answer:
why cant she just be like "ooh yummy lasagna" and move on lol
Step-by-step explanation:
the mean (average) of three boys is 40 pounds. one of the boyd weighs 50 pounds. the other two boys have the same weight. find weight of each of the boys
Answer:
35, 35, and 50
Step-by-step explanation:
50 + x + x = n
n ÷ 3 = 40
n = 40 x 3
n = 120
50 + 2x = n
50 + 2x = 120
2x = 120 - 50
2x = 70
2x/2 = 70/2
x = 35
To check:
35 + 35 + 50 = 120
120 ÷ 3 = 40
Hope this helps
Answer:
35
Step-by-step explanation:
let us take each boy's weight as x
therefore,
average = [tex]\frac{x+x+50}{3\\}[/tex]
40 = [tex]\frac{x+x+50}{3\\}[/tex]
40 x 3 = x + x + 50
120 - 50 = 2x
70 = 2x
2x = 70
x = [tex]\frac{70}{2}[/tex]
x = 35
So weight of each boys is 35.

Answer:
$1
Step-by-step explanation:
To find out how much more money Olivia spent per apple, we need to find out how much each spent on one apple.
Cassie:
2 apples --- $4
1 apple --- $4 ÷ 2 = $2
Olivia:
5 apples --- $15
1 apple --- $15 ÷ 5 = $3
Difference per apple = $3 - $2
= $1

Answer:
1). x = 14
2). y = 2.4 cm
Step-by-step explanation:
In the diagram ΔNPQ ~ ΔNLM and NL = 3,
1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]
(3x + 18)° = 60°
3x = 60 - 18
x = 14
2). Since, both the triangles are similar, corresponding sides will be proportional.
[tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]
[tex]\frac{y}{3}=\frac{3.2}{4}[/tex]
y [tex]=\frac{3.2\times 3}{4}[/tex]
y = 2.4 cm
The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square is equal to the octagon. Find the length of the square and the length of a side of the octagon.
Please show work, I will give brainliest.
9514 1404 393
Answer:
square: 12 ft sidesoctagon: 6 ft sidesStep-by-step explanation:
This problem can be worked in your head.
If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.
__
We can let s represent the side length of the octagon. Then we have ...
8s = perimeter of octagon
4(s +6) = perimeter of square
These are equal, so ...
4(s +6) = 8s
s +6 = 2s . . . . . . divide by 4
6 = s . . . . . . . . . . subtract s
The octagon has 6-ft sides; the square has 12-ft sides.
