3(x+2)(3x-1)=3•(x+2)•(3x+1).
1. Distribute the 3 across x+2 to get (3x+6)•(3x-1)
2. Distribute the 3x term from the first expression across the 3x-1. And then do the same with the 6.

9x^2-3x+18x-6

And then combine like terms

9x^2+15x-6

Solve for a a^2+17=42?

grandymaker [24]

We are given the following equation:

$a^2+17=42$

$a^2=25$

Take the positive/negative square root of both sides

$a=\pm5$

This should be your answer. Let me know if you have any questions, thanks!

Jenny and her friends are hungry for dessert. They buy $12.25 worth of cookies and ice cream sandwiches. The ice cream sandwiche

Phoenix [80]

If the number of ice cream sandwiches is x

And the number of cookies is y

Then

1.75x + 0.75y = 12.25

and

x + y = 11
y = 11 - x

1.75x + 0.75 (11 - x) = 12.25
1.75x + 8.25 - 0.75x = 12.25
x + 8.25 = 12.25
x = 12.25 - 8.25
x = 4

if x = 4

4 + y = 11
y = 11 - 4
y = 7

x = 4, y = 7
