Evaluate 7^2 + (4x5) - 2^3

1 answer:

8 0

Remember PEMDAS! Do the parenthesis first so 4x5 is 20. So now write it out as 7^2+20-2^3 now next is exponents. 7x7 is 49 and -2x-2x-2 is -8. now write it as 49+20+-8. Now solve from left to right. 49+20 is 69 now subtract 8 which is 61. 61 is your answer! I hope this worked!

How do i solve for x?

Answer:

x = 6

Step-by-step explanation:

We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.

We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.

If we were to turn that into an equation it would like like this:

(9x + 4) + 32 = 90

Now you just have to solve for x.

9x + 4 + 32 = 90

Combine like terms:

9x + 36 = 90

Subtract 36 from both sides

9x = 54

divide both sides by 9

x = 6

and you are left with the answer.

Need help in this mathquestion. The function h(x)=(x+2)^2 can be expressed in the form f(g(x)) where f(x)=x^2 , and g(x) is defi

Answer:

In a nutshell, $g(x) = x+2$ .

Step-by-step explanation:

A composition is operation between function that consist in replacing the independent variable of the first function, $f(x)$ in this case, for $g(x)$ . Common notations for composition between functions are $f(g(x))$ and $f\circ g (x)$ . If we know that $h(x) = f\circ g (x) = (x+2)^{2}$ and $f(x) = x^{2}$ , then $g(x) = x+2$ .
