Hey there! Our goal here is to isolate the variable on one side of the equation.
Answer:
4
Step-by-step explanation:
Make the 10% a decimal
.10
Then multiply it by 40
.10*40
You get 4
I would assume it would be dividing both sides by three although if someone were to actually solve this I would say multiply 2 and 3 together first.
Hope this helps :)
Answer:
(x−2)(x−4)
Step-by-step explanation:
Let's factor x2−6x+8
x2−6x+8
The middle number is -6 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -6
Multiply together to get 8
Can you think of the two numbers?
Try -2 and -4:
-2+-4 = -6
-2*-4 = 8
Fill in the blanks in
(x+_)(x+_)
with -2 and -4 to get...
(x-2)(x-4)
Hope this helps! Also, if it's no trouble, can I have brainliest? Thanks! :D
