Answer:

3x²+8x-35

Step-by-step explanation:

<u>FOIL stands for:</u>

First -> (3x-7)(x+5)

Outer -> (3x-7)(x+5)

Inner -> (3x-7)(x+5)

Last -> (3x-7)(x+5)

Following FOIL, we get:

(3x-7)(x+5)

(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)

3x²+15x-7x-35

3x²+8x-35

Therefore, the expanded form is 3x²+8x-35

bija089 [108]

The daily consumption rate in the United States will be 10 barrels per person.

Your question is incomplete as you didn't provide the total barrels, therefore, an overview of the answer will be given. In their case, let's assume that the total barrels is given as 3.1 billion.

The sum of two numbers is 27. The larger number is 6 more than twice the smaller number. What are the numbers?
yawa3891 [41]

Answer:

Let the smaller number be x

Then the sum is

(6 + 2x) + x = 27

We now find for x

2x + x + 6 = 27

3x + 6 = 27

3x = 27-6

3x = 21

x = 21/3

x = 7

Therefore the smaller number is 7

The larger number is (2×7) + 6 = 20
