A rectangle has a length of x and a width that is 8 units shorter than twice the length.
a. Draw a picture to represent the box.
b. Write a simplified polynomial to represent the area of the rectangle.
c. What would the area be if = 10 ?

Answers

Answer 1

Step-by-step explanation:

length = x

width = 2x-8

b.) to get the area you need to multiply the length and the width.

l×w= area

x(2x-8)

2x^2-8x

c.) 2x^2-8x = 10

subtract 10 both sides

2x^2-8x-10 = 0

2(x^2-4x-5) = 0

2(x-5)(x+1) = 0

x = 5

the area would be 10.

TV−→− bisects ∠STU, m∠STV=(14x+8)∘, and m∠UTV=(x+2)∘. Find m∠STU

Answers

Answer:

Since TV bisects STU, m∠STV and m∠UTV are equal

14x+8 = x+2

13x+8 = 2

13x = -6

x = -6/13 or -0.46

The measure of m∠STU is 40/13 degrees

A point that bisects a line divides the line into two equal parts

If TV bisects  ∠STU and  ∠UTV, then;

∠STU =  ∠STV+  ∠UTV ∠STV=  ∠UTV

Given the following

m∠STV=(14x+8)∘

m∠UTV=(x+2)∘

Substitute the given values into the formula and calculate m∠STU

14x + 8 = x+ 2

14x - x = 2 - 8

13x = -6

x = -6/13

Get m∠STV

m∠STU = 14x+8 + x + 2

m∠STU = 15x + 10

m∠STU = 15(-6/13) + 10

m∠STU = -90/13 + 10

m∠STU = 40/13

Hence the measure of m∠STU is 40/13 degrees

You want to purchase your first house. A conventional mortgage will require a credit score of approximately 630. Your credit score is 560. You need to increase it by 70 points to get to 630. If you increase your score by 12% per year, how many years will it take to lift your score to 630?

Answers

Answer:

a) 1.1 yrs

Step-by-step explanation:

THESE ARE OPTIONS FOR THE QUESTION BELOW;

a) 1.1 yrs

b) 2.3 yrs

c) 26 yrs.

d) 12 yrs.

✓At initial year (0 year) credit score =560 points

Then the score is increased by 12% per year, with this 12% increase we have 702.4 points in the 1st year

✓At the first year(1st year)

(12/100)× 560 points of the initial year.

= 627points

✓ At second year (2nd year), the 627points

increases by 12% again.

(12/100)× 627.2 points of the initial year.

= 702.4points

There was 75.2 increase between istyear and second year(702.4points - 627points)

Since, We have 12 month in a year, that means there is 6.2 points per month (75.2/12) for the year .

After second year we had 627points, with increase of 6.2point, Then at 1.1 year we would have score of 630 points

Answers

Answer:

x = -4u/3

Step-by-step explanation:

The first step is to create a fraction on both sides in order to prepare for cross-multiplication.

Cross-multiplication is a shortcut for the following technique, shown by this example.

a/b=c/d

Multiplying both sides of the equation by bd using the multiplication property of equality will then grant the equation ad = bc, and then a single component can be isolated by creating the equation a = bc/d for example using the division property of equality.

Back to cross-multiplication, however, creating a fraction of both sides can be achieved by creating the equation u/1 = -3x/4, since any number divided by 1 is equal to itself.

Then, by cross-multiplying u and 4 and 1 and -3x, you get the equation 4u = -3x.

Dividing both sides by -3 will then grant the final answer of x = -4u/3.

Answers

Answer:

6

Step-by-step explanation:

7x + 3(-x + 6) = 42

use distributive property

7x + -3x + 18 = 42

positive + negative = negative

7x - 3x + 18 = 42

combine like terms

4x + 18 = 42

subtract 18 from both sides

4x + 18 - 18 = 42 - 18

18 is canceled out on the left side

4x + 0 = 24

4x = 24

divide both sides by 4

4x ÷ 4 = 24 ÷ 4

1x = 6

x = 6
