Question

Evaluate 7+ (-4x^2) for x = 0

Answer 1

If x is zero then you must replace x with zero and use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction) to solve

7 + (-4(0)^2)

7 + (-4(0))

7 + 0

7

If x is 0 then the expression equals 7

Answer 2

Answer:

$\boxed{7}$

X=0 is 7.

7 is the correct answer.

The answer should have a positive sign.

Step-by-step explanation:

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

from left to right.

Distributive property: a(b+c)=ab+ac

$7+(-4x^2)$

$7+-4x^2$

$7-4*0^2$

Do exponent.

$0^2=0*0=0$

$7-0=7$

7 is the correct answer.

Hope this helps you!
