One solution would be 12-3=9, because if you're trying to find x, you have to use what's given, which is 12 and 3 and since it's giving you something with addition then you have to use the inverse operation. The inverse operation would be subtraction.
699 is closet because as you subtract every number from 750, the smallest answer given is the closest to the number you started with.
Answer for Question #1.
The equation use to find the length of the base of a triangle is
![56= \frac{1}{2}(x)(x+6)](https://tex.z-dn.net/?f=56%3D%20%5Cfrac%7B1%7D%7B2%7D%28x%29%28x%2B6%29)
.

Answer for Question #4.
The width of the new garden is 12 m.
Answer for Question #5.

Answer:
Step-by-step explanation:
A ratio problem
230 sides is to 147 height as 220 sides is to an unknown height X
230/147 = 220 / X solve for x ( since 220 < 230 X should be < 147)
X = (220)(147) / 230
X = height = 140.6 m is less than 147
