Answer:
3
Step-by-step explanation:
First, multiply the bread cost 2.70 by 2, getting you 5.40.
Next, add 11 for the cost of the caketo 5.40 getting you 16.40
Subtract 16.40 from 20 to get how much money you get for the cookies, getting you 3.60
Divide 3.60 by 3 to find how much money each boy gets, getting you 1.20
Divide 1.20 by .40 to get the number of cookies each boy gets, getting you 3

Step-by-step explanation:
157.5/21 = 7.5
To get in hundredths form you need to multiply both the numerator and denominator by 10. 6×10=60 and 10×10=100
The answer is 60/100
We are given expression: 
.
Square root in exponent form is power 
.
Therefore, 
.
Now, replacing square root of 16 by 
in original expression we are given, we get
.
Therefore,
<h3>
= 16 in simplest form. By the Power of Power rule,
. So,
must equal
in radical form.</h3>
Answer:
2x³ + 3(3x - 4)(x + 1)
Step-by-step explanation:
(2x³ + 7x² + x) + 2(x² - 2x - 6)
2x³ + 7x² + x + 2x² - 4x - 12
2x³ + 9x² - 3x - 12
2x³ + 3(3x² - x - 4)
2x³ +3(3x - 4)(3x + 3)/3
2x³ + (3x - 4)(3x + 3)
2x³ + 3(3x - 4)(x + 1)
