Answer:
40 ft
Step-by-step explanation:
<em>Data:
</em>
(1) P = 120 ft
(2) l = 2w
<em>Calculations:
</em>
(3) P = 2l + 2w Substitute (1) and (2) into (3)
120 = 2(2w) + 2w Multiply
120 = 4w +2w Combine like terms
120 = 6w Divide by 6
(4) w = 20 ft Substitute (4) into (2)
l = 2 × 20
l = 40 ft
<em>Check:
</em>
120 = 2×40 + 2×20
120 = 80 + 40
120 = 120
Answer:
7. x = 10

Step-by-step explanation:
Explanation for Number 7.
The exterior angle is always equl to the sum of the two opposite interior angles.
The two opposite interior angles: 62 and (7x + 14)
The exterior angle: (15x - 4)
So you would set it up like _____ = ______ to solve for x
62 + (7x +14) = 15x - 4
62 + 7x + 14 = 15x - 4
Then move the terms
76 + 7x = 15x - 4
Collect the like terms and Calculate
7x - 15x = -4 - 76
Divide both Sides
-8x = -80
/8 /8
-x = -10
/-1 /-1
x = 10
Hope this helps ^^
