Answer:
the perimeter is 50 inches squared
Step-by-step explanation:
if the length is 4 times that means the sides are 20 and 5
Answer:
x = -10; x = 7
Step-by-step explanation:
|2x + 3| - 6 =11
Add 6 to each side.
|2x + 3| = 17
Apply the absolute rule: If |x| = a, then x = a or x = -a.
(1) 2x + 3 = 17 (2) 2x + 3 = -17
Subtract 3 from each side
2x = 14 2x = -20
Divide each side by 2
x = 7 x = -10
<em>Check:
</em>
(1) |2(7) + 3| - 6 = 11 (2) |2(-10) + 3| - 6 = 11
|14 + 3| - 6 = 11 |-20 + 3| - 6 = 11
|17| - 6 = 11 |-17| - 6 = 1
1
17 - 6 = 11 17 - 6 = 11
11 = 11 11 = 11
Answer:
y = x-4
Step-by-step explanation:
you can put it in a calculator to be sure
2x + 3/12 = 2x/8
2x - 2x/8 = -3/12
2x - x/4 = -3/12; 2 - 1/4 = 1 3/4 = 7/4
7x/4 = -3/12
7x = -3/12 * 4
7x = -1
x = -1/7
