Ok, I don't have a question, so I am just doing this for fun. This is for 7th-8th graders, I am higher than those grades

If x=3, what is the value of :(4x^2)+5^2?

61

Step-by-step explanation:

If you use

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

or PEMDAS, you will eventually get 61

Substituting x

(4*3^2)+5^2=            (Use Exponents first)

(4*9)+5^2=                (Use Parentheses now)

(36)+5^2=                  (You can get rid of the Parentheses)

36+5^2=                    (Use Exponents again)

36+25=                      (Now Addition)

61

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
