Answer:
x=-1
Step-by-step explanation:
4x-16=-20
Get x to one side by subtracting it.
-16=-20-4x
Add the 20 on both sides.
-16+20=-4x
Simplify
4=-4x
4/-4=-4x/-4
-1=x
x=-1

<u>1.Example, x²-25 can be factored as (x+5)(x-5).</u>

<u>2.This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).</u>
<u>

<u>3.When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5).</u>

Answer:
5 oranges
Step-by-step explanation:
to solve this problem we need to make a cross-multiplication equation
2.34 is to 6 as 1.95 is to ?
? is the number of oranges that are needed to be found that were bought
2.34/6 = 1.95/?
Now we cross multiply 6 and 1.95 = 11.7
11.7/2.34 = 5
Give brainliest, please!
hope this helps :)
1-2 is right
3 you have to draw a shape and then put 3 lines then shade in one
number 4 you have to draw a shape again but put 8 lines through then shade 1
5 your answer is 1/8
6 your answer is 1/4
7 you have to draw a shape again draw 3 line in the shape then shade 1 and your fraction is 1/3
