Which expression is equivalent to (x2 − 3) − (− 3x2 + 5)?

A) 4x2 − 8
B) 4x2 − 2
C) −2x2 − 2
D) −2x2 − 8

4x2-8

Step-by-step explanation:

This question requires a step by step procedure

Ensure that you don't miss any steps so as to get the right answer

So let's solve the given question

(X2-3)-(-3x2+5)

Let's start by dealing with the bracket first

(X2-3)+3x2-5

X2-3+3x2-5

Collect like terms

X2+3x2-3-5

4x2-8

So the answer is 4x2-8

But in the case where we are asked to solve further we can actually equate the equation to zero

4x2-8=0

4x2=8

Divide both sides by 4

X2=2

Square root both sides

X=√2

But since we are not asked to solve further,our final answer is 4x2-8

I believe this will help you

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
