The mistake she made was saying it was a $25 discount when in the equation it said adding 25, and discount is subtraction so that is the mistake.

the new equation is 9x-25=88

Answer:

1024x^{40}

Step-by-step explanation:

So the first step is to add like terms since you can simplify the numerator by adding the two values sine they have the same variable and degree.

Add like terms:

[\frac{8x^9}{2x}]^5

Divide by 2x (divide coefficient by 2, subtract coefficient degrees)

[4x^8]^5

Multiply exponents and raise 4 to the power of 5

1024x^{40}

The reason you multiply exponents is because you can think about it like this:

(4 * x * x * x * x * x * x * x * x) (this has one 4 and 8 x's because x is raised to the power of 8. Now if you do that 5 times which is what the exponent is doing you're going to have 40 x's and 8 4's. So it's essentially

(4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x) * (4 * x * x * x * x * x * x * x * x). If you group like terms you'll get (4 * 4 * 4 * 4 * 4) *  (x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x * x). Which simplifies to 4^5 * x ^ (8 * 5) which further simplifies to the answer 1024x^40

Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals
Natalija [7]
The two diagonals intersects at right-angle for a kite

the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3

QPR is a right-angle triangle with QR at 5 and QR at 3

RP = sqrt (5^2 - 3^) = 4m

Find x and y. <br><br> please help !
IrinaK [193]

Using linear pairs,

115+5x=180\\\\5x=65\\\\x=\boxed{13}

By the exterior angle theorem,

2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}

sattari [20]

Hi! For this question all you have to do is subtract 43 from 72.

72 - 43 = 29

Trina had 29 stamps left.

Hope this helps! Happy Thanksgiving!
