FOR 100 POINTS!!!!!!!!!!! Solve the equation. 3(4x + 4) = 2(5x + 9) - 12

Tatiana [17]

Answer:

Step-by-step explanation:

Isolate x on one side of the equation.

DISTRIBUTIVE PROPERTY

A(B+C)=AB+AC

A(B-C)=AB-AC

3(4x+4) (First, expand.)

3*4x=12x

3*4=12

12x+12

2(5x+9)-12

2*5x=10x

2*9=18

10x+18

18-12=6

12x+12=10x+6

12x+12-12=10x+6-12 (Subtract 12 from both sides.)

6-12 (Solve.)

12-6=6

12x=10x-6

12x-10x=10x-6-10x (Subtract 10x from both sides.)

12x-10x (Solve.)

12x-10x=2x

2x=-6

2x/2=-6/2 (Then, divide by 2 from both sides.)

-6/2 (Solve.)

-6/2=-3

x=-3

As a result, the final answer is x=-3.

Integrate (x^3)/(a^2)-(x^2) ?

notka56 [123]

Hi!

$\frac{x^3}{(a^2)-(x^2)}$

First remove parenthesis.

$\frac{x^3}{a^2-x^2}$

Factor $a^2-x^2$ or $(x+a)(a-x)$

$=\frac{x^3}{(a+x)(a-x)}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

Solve for m and n I been stuck on this question for an hour

Crazy boy [7]

Answer:

m = 10 , n = 5 $\sqrt{2}$

Step-by-step explanation:

using the cosine and tangent ratio in the right triangle and the exact values

cos45° = $\frac{1}{\sqrt{2} }$ and tan45° = 1 , then

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{5\sqrt{2} }{m}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

m = 5 $\sqrt{2}$ × $\sqrt{2}$ = 5 × 2 = 10

-----------------------------------------

tan45° = $\frac{opposite}{adjacent}$ = $\frac{n}{5\sqrt{2} }$ = 1 , then

n = 5 $\sqrt{2}$
