The perimeter of a triangle is when u add all of the sides together
(8x - 7w) + (2x + 6y) + (3y + 5w) =
10x + 9y - 2w is ur perimeter

8w + 12x - 9y
8w + 12x - 9y
8w + 12x + 5y
8w + 12x - 9y

the 1st, 2nd, and 4th answer choices are the same....so 3 of them are equal

Whats the GCF of 49 and 4

Irina18 [472]

The greatest common factor is 1 because there is not a number that goes into or will multiply and get 49 and 4. 49 is an odd number and 4 is an even number so the GCF is 1.

A stairway rises 6 feet 4 inches over a horizontal distance of 8 feet 6 inches. What is the diagonal length of the stairway

natali 33 [55]

Answer:

10.6 ft

Step-by-step explanation:

to find the diagonal length of the stairway we can use the pythagorean theorem or a^2 + b^2 = c^2

6'4" is also 6 1/3' or 19/3'

8'6" is also 8 1/2' or 17/2'

now square them both

361/9 + 289/4

make them have the same denominator

1444/36 + 2601/36

add them

4045/36

take the square root

10.6000524 is your answer

10.6 ft

∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ ∠A=(4x−16) ∘ and m ∠ B = ( 8 x + 4 ) ∘ ∠B=(8x+4) ∘ , then find

inna [77]

Answer:

∠ A = 48°

Step-by-step explanation:

Supplementary angles are those angles that measure up to 180 degrees.

∠A and ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ and m ∠ B = ( 8 x + 4 ) ∘,then find the measure of ∠ A

Step 1

∠A + ∠B = 180°

(4x−16)° + (8x+4)° = 180

4x - 16 + 8x + 4 = 180

12x -12 = 180

12x = 180 + 12

12x = 192

x = 192/12

x = 16

Step 2

To find the measure of ∠ A

∠ A = 4x - 16

= 4 × 16 - 16

= 64 - 16

= 48°

Therefore,

∠ A = 48°

Point R on the coordinate grid below shows the location of a car in a parking lot. A second car needs to park 6 units above R to

Over [174]

Answer:

$R' = (-4 , 4)$

Step-by-step explanation:

Given

See attachment for the grid coordinate

From the attachment, we have that:

$R = (-4,-2)$

Required

Determine the coordinates of the second truck

Represent the position with R'

From the question, we understand the position of R' is 6 above R

When a point (a,b) is moved n point above, the new point becomes (a, b + n)

So:

$R = (-4,-2)$

When moved 6 points above becomes:

$R' = (-4 , -2 + 6)$

$R' = (-4 , 4)$

<em>Hence, (-4,4) answers the question</em>
