If f(x) = 4x2 + 1 and g(x) = x2 - 5, find (f - g)(x). O A. 34² - 4
O B. 3x2 + 6
C. 5x2 - 6
O D. 5x2 - 4

B.

Step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
