I’m doing test corrections and they are due tomorrow. i don’t know how to do this.

x = 22 mm

Step-by-step explanation:

The area of a kite is one-half of the product of the max width and max height.

A = (1/2)(a)(b)

We are given the height and the area, and need to find the width.  Plug in the given values and solve.

247.5 = (1/2)(22.5)(b)

    495 = (22.5)(b)               (multiply both sides by 2 to get rid of the fraction)

       22 = b                         (divide both sides by 22.5 to isolate b)

The width is 22 mm across

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
