Answer:
Linear equations are used to calculate measurements for both solids and liquids. An electrical engineer, for example, uses linear equations to solve problems involving voltage, current and resistance.
Step-by-step explanation:
500 + 30g <span>≤ 8000
30g </span><span>≤ 7500
g </span><span>≤ 250</span>
The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.
Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.
1 is B.
2 is x > 3
4 is d+0.06d
I don't know 3, but I'll ask it for you, since you don't have many points.
The equation that is true is D
