Answer 1
Answer: Hello!

You can plug the answers in for x and see if it is right

x^2 + 8x = 33

-11^2 + 8(-11) = 33

121 - 88 = 33

3^2 + 8(3) = 33

9 + 24 = 33

So the answer is the first one

Hope this helps!
Answer 2
Answer: x^2 + 8x = 33 \n x^2 + 8x + ( (8)/(2))^2 = 33 + ( (8)/(2))^2 \n x^2 + 8x + 16 = 33 + 16 \n (x + 4)^2 = 49 \n x + 4 = \pm 7 \n x = 7 - 4 = 3 \n x = -7 - 4 = -11

Your answers are {3, -11}

What can be multiplyed by 3 to equal 40

Answers

Let's say that the number we are looking for is called 'x'.

3 * x = 40
3x = 40

To solve for 'x', we will need to divide both sides by 3.

3x/3 = 40/3

x = \boxed{\bf{(40)/(3) = 13(1)/(3)}}

40/3 or 13 1/3 can be multiplied by 3 to get 40.

Solve (if you can (ha ha ha)).

x^7-128=0

Answers

Step 1: Add 128 to both sides.
x^7−128+128=0+128
x^7=128
Step 2: Take root.x=(128)^(1/7)
x=2
Answer:
x=2
x^7 -128= 0
⇒ x^7 -2^7= 0 (because 2^7= 128)
⇒ x^7= 2^7
⇒ x= 2

The final answer is x=2~

The costa Family hiked a trial that was two miles in one direction How many feet was the hike round trip?

Answers

Since the costa family hiked two miles in one direction. You have multiply 2+2 to find the round trip. You get 4, but that isn't the answer because it is in miles not feet. You have to multiply 4 x 5280, because there are 5280 feet in one mile.  You get 21120 feet. Hope this helps. :-)
