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

: 4.1B; 4.10B)
Paha777 [63]

Answer:

C. $16.00

Step-by-step explanation:

First, let's find how much they profit from one loaf

The profit is the difference between how much they sell it for and what they buy it for.

So, we can subtract what they buy the bread for from how much the sell it for

selling price-buying price

2.40-0.80=1.6

So, they profit $1.60 per loaf

To find how much they profit for 10 loaves, multiply their profit from one loaf by 10

profit*10

1.60*10=16

The profit for 10 loaves is $16, or choice C
