A rectangle has a height of k2 + 3 and a width of k2 + 7.

Express the area of the entire rectangle.

Your answer should be a polynomial in standard form.

k2

2

+

The area of the rectangle in polynomial form is

Step-by-step explanation:

Given

Shape: Rectangle

Required

Area of the rectangle

The area of a rectangle is calculated as thus;

By substituting for height and for width; This gives

Expand the bracket

Open each bracket

Hence, the area of the rectangle in polynomial form is

so, converting firstly the mixed fractions to improper fractions and then "adding".

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
