Answer:

see below

Step-by-step explanation:

(3x + 8) units by (6x + 5) units.

A = l*w

= (3x+8)(6x+5)

Distribute

3x*(6x+5) + 8(6x+5)

18x^2 +15x + 48x +40

Combine terms

18x^2+63x+40 units^2

The degree is 2 ( the highest power of x)

This is a trinomial ( it has 3 terms)

Multiplication is closed for polynomial multiplication

We started with polynomials and we ended up with a polynomial.

WHOEVER GETS THIS RIGHT IN 3 MINUTES GETS THE BRAINLIEST!! Four times the sum of a number and 15 is at least 120. Let x represen

larisa [96]

Hey there!

Let's call this "number" x. We want four times the sum of this number and 15 to equal at least 120.

Therefore, we want this number times four plus fifteen to be greater than or equal to 120. We have:

$4(x+15)\geq 120$

Distribute:

$4x + 60 \geq 120$

Subtract:

$4x\geq 60$

Divide:

$x\geq 15$

Your answer is C.

Hope this helps!
