Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as (x^2+4)^2+32=12x^2+48.

We can simplify the expression using the term a by replacing x^2 + 4 with a.

(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0                 a=4

a-8=0                   a=8

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=(a+b)/2 h Solve for a.
yKpoI14uk [10]

Answer:

a=\frac{2A}{h}-b

Step-by-step explanation:

Hello, I think I can help you with this.

According to the information provided in the problem, the area of ​​a trapezoid is given by

A=\frac{a+b}{2} *h\\

Step 1

solve for a, it means isolate a

A=\frac{a+b}{2} *h\\divide\ both\ sides\ by\ h\\\\\frac{A}{h}= \frac{\frac{a+b}{2} *h}{h} \\\frac{A}{h}=\frac{a+b}{2}\\\\Now, multiply\ both\ sides\ by\ two\\\\ 2*\frac{A}{h}=2*\frac{a+b}{2}\\2*\frac{A}{h}=a+b\\\frac{2A}{h}=a+b\\\\subtract\ b\ for\ both\ sides\\\frac{2A}{h}-b=a+b-b\\a=\frac{2A}{h}-b

Have a good day.

What is the solution to the system of equations below?
katen-ka-za [31]

4x  - y =  - 5 \\  - 2x + y = 3

Solve the second equation for y

4x - y =  - 5 \\ y = 3 + 2x

Substitute the given value of y into the first equation

4x - (3 + 2x) =  - 5

Solve the equation for x

x =  - 1

Substitute the given value of x into the second equation

y = 3 + 2( - 1)

Solve the equation for y

y = 1

The possible solution of the system is the ordered pair (x,y)

(x,y) = ( - 1, 1)
