Step-by-step explanation: It is 13x to the 2nd power plus 5x minus 8

Answer:

-26x

Step-by-step explanation:

(9x)(2-8)-(4x)(2-5x)

^separating x so i can distribute but the ones that are sitting weirdly in the  parentheses (see how there isnt a sign separating 9x and 2? im going to seperate them via parentheses which is the same thing as adding a sign there. Same with -4x and 2)

we are going to distribute now. 9x*2, 9x*-8 -4x*2 -4x*-5x

(18x-72x) - (-8x+20x)

Its going to look like this ^

add or subtract the stuff in the parentheses

-54x+28x

-26x

For your birthday you get a big cake and cut it into several pieces. At the end of the party you have 12 pieces of the cake left which is 3/8 of the total cake. How many pieces was the cake originally cut into? Write and solve an equation.

Answers

Answer:

32 pieces

Step-by-step explanation:

1 - 3/8 = (8 - 3) / 8 = 5/8

3/8 = 12 pieces

5/8 = x

Cross multiply

3/8 x = 12 * 5/ 8

3/8 x = 7.5

x = 20

Hence, total piece cake was cut into originally :

20 + 12 = 32 pieces
