Answer:
Step-by-step explanation:
-2x + 8 = 4
-2x = 4 - 8
-2x = - 4
x = - 4/-2 = 2
replace x with 2 on the equation
-4-4=4
so answer is no
-8=4 not possible
What is 234475 x 45678 =?
pq=3-a√x
make x the subject
Step-by-step explanation:
pq = 3 - a√x
Making x subject
a√x = 3 - pq
√x = (3 - pq) / a
x = [ (3 - pq) /a ]²

This a morning work and I don't get when they say "Area of a triangle" I'm still working on it, but Im just so confused. Can you help?
Answer:(b) 100^2in
Step-by-step explanation: Well 1st area means inside so they wanted you to find the inside, and well the answer is 100 hope it helped :)
Please help asap!!!!
Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
es aquel que esta conformado por la totalidad de elementos en estudio
Simplify the expression so there is only one positive power for the base, -5.

i dont know functions
Answer:
6, -8
Step-by-step explanation:
You need to find out the possible values of which X cannot equal
In fractions the only way that's possible is if the denominator= 0
Because everything in the denominator is being mulitplied this is pretty simple
We need either parantheses to equal 0
so we take them and solve for 0
we have
x-6= 0
x=6
x+8=0
x= -8

4y square + y - 45 when y=-5
Given:
The expression is
[tex]4y^2+y-45[/tex]
To find:
The value of the given expression when y=-5.
Solution:
We have,
[tex]4y^2+y-45[/tex]
Putting y=-5, we get
[tex]4(-5)^2+(-5)-45[/tex]
[tex]=4(25)-5-45[/tex]
[tex]=100-50[/tex]
[tex]=50[/tex]
Therefore, the value of the given expression is 50 when y=-5.

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Answer:
55 = 5x
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Equation to model this situation in the form y = mx + b,
y = Total number of stickers she had
x = Number of days that she gave away sticker
b = Fixed value = 0
Hence:
55 = 5x + b
b = Fixed value = 0
Therefore, the situation is represented as:
55 = 5x
find the missing length of 26cm 10cm of the right triangle
Answer:
24cm
Step-by-step explanation:
A^2 + B^2 = C^2 soo 10^ + B^ = 26^2 so 100 + B^2 = 676 subtract 100 from 676. Then take the square root of 576 and you’ll get 24. So B = 24cm
