Answer: $x^3y^9$

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): Dot was discarded near "7.".

STEP 1:

Simplify $\frac{y^2}{x}$

The equation at the end of step 1:

$((x^4)*\frac{y^2}{x} )*y^7$

Multiplying exponential expressions:

2.1 $y^2$ multiplied by $y^7$ $=y^(2+7)=y^9$

Final result is $x^3y^9$

Step 1: 12x – 15 – 12x = 7x + 20

stealth61 [152]

Step-by-step explanation:

step 1. 12x - 15 - 12x = 7x + 20

step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)

step 3. -15 = 7x + 20 (adding like terms)

step 4. -35 = 7x (subtract 20 from both sides)

step 5. this step is incorrect.

step 6. -5 = x ( divide both sides by 7)

step 7. x = -5 (put the variable first).

June drove 116 miles and 5.8 hours at this rate how far will she drive in 5 hours

Sonbull [250]

First we need to calculate how fast she was going in one hour:
116 / 5.8 = 20

then multiply that by 5 to get how far she will go in 5 hours

20 * 5 = 100

Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) $9^{2} + 12^{2}$ = 225

$15^{2}$ = 225

2) $15^{2} + 36^{2}$ = 1521

$39^{2}$ = 1521

3) $10^{2} + 26^{2}$ = 776

$28^{2}$ = 784

4) $10^{2} + 12^{2}$ = 244

$16^{2}$ = 256
