Answer:

64a^{3} b^{6}

Step-by-step explanation:

1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:

(4ab^{2} )^3

4^{3} · a^{3} · b^{6}

2) The variables are fine - you can't simplify them further. All you need to do now is multiply the 4^{3} out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"

4 · 4 · 4 · a^{3} · b^{6}

16 · 4 · a^{3} · b^{6}

64a^{3} b^{6}

Therefore, 64a^{3} b^{6} is the answer.

Answer:

9) x=58

10) r=4

11) m=4

12) p=3

13) x=6

14) x=-3

15) s=400

Step-by-step explanation:

9) x+2/5=12

    x5  x5

x+2=60

 -2  -2

x=58

10) 7r + 14 - 3r =30

    -14         -14

<u>7r-3r</u>=16

4r=16

÷4 ÷4

r=4

11) \frac{4}{5}m+2=6

    -2  -2

\frac{4}{5}m=4

÷\frac{4}{5}  ÷\frac{4}{5}

m=4

12) <u>2</u>(5p+9)=48

10p+18=48

     -18  -18

10p=30

÷10  ÷10

p=3

13) <u>5</u>(2x-8)=20

10x-40=20

    +40 +40

10x=60

÷10  ÷10

x=6

14)<u>6</u>(3-2x)=54

18-12x=54

-18       -18

-12x=36

÷-12  ÷-12

x=-3

15) \frac{2s}{5}-\frac{s}{2}=40

x5   x5

2s-\frac{s}{2}=200

    x2 x2

<u>2s-1s</u>=400

1s=400

÷1  ÷1

s=400

(x +y )(x -y), if x = -3, y=-5<br> PLS NO FILES OR I AM REPORTING YOU
luda_lava [24]

Answer:

-16

Step-by-step explanation:

(X + Y)

= (-3 + -5)

= -8

(X - Y)

= (-3 - -5)

= 2

Because  they're still in brackets in this form:

(-8) (2)

You multiply them both and you'll get the answer:

-16

hope this helped!
