A rectangle has a height of 7x’ and a width of 3x2 + 8x + 7 Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
3x2
830
+
7z?
Area =
?

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
