Answer:

Step-by-step explanation:
In order to solve this problem, lets take the two terms in the binomial (4x and -3) and, for each one, multiply them by each term in the trinomial (2x^2, -7x, and 1):




Let's combine like terms to get our final answer:


Area of a circle=πr²
r=radius=13 cm
area of a circle=π(13 cm)²=169π cm²≈530.93 cm²≈530.7 cm²
Answer: B.530.7 cm²
5, 10 ,15
divide each by 5
1,2, 3
so the ratios should be 1,2,3
Metal 1 : divide by 150
1,2,4
Metal 2 divide by 130
1,2,3
Metal 3 divide by 310
1,2,3
Metal 4 divide by 140
1,2,3
Metal 1 is not proportional
Choice A
