Hey again!
The answer to your question is 98 feet squared
First, we find the new dimensions:
7 x 2 = 14
3.5 x 2 = 7
Area = length x width, so 14 x 7 = 98
Hope it helps!
Answer:
6.50
Step-by-step explanation:
- 10.00
P=$5a+$3c
$85 = $5a+$3(20)
$85 = $5a + $60
$85-$60 = $5a + $60-$60
$25 = $5a
$25/$5 = $5a/$5
a = 5
Check
P=$5a+$3c
$85=$5(5)+$3(20)
$85=$25 + $60
$85=$85
Answer:
32.975
Step-by-step explanation:
<u>Answer:</u>
9. x = 12
10. x = 31
<u>Step-by-step explanation:</u>
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
<u>Check:</u>
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
<u>Check:</u>
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180
