Answer:
2/3
Step-by-step explanation:
Since the length increases by 0.5 cm every second, after 8 seconds the length will increase by 4 cm. 12 + 8 + 12 + 8 = 40, and 40 - (16 + 16) = 8. 8/2 = 4, so the width is now 4. 16 * 4 = 64, and 12 * 8 = 96. 64/96 = 2/3.
Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
The answer is 61. hope that help.
A = d1(d2) / 2
A = 12(14) / 2
A = 168 / 2
A = 84 square inch
