Simplify 2(x-4)+7(x+2).
2 answers:
Answer:
3(3x+2)
Step-by-step explanation:
Isolate the different parts of the expression and simplify them individually.
2(x-4) and 7(x+2)
Distribute the 2 and 7 into each of the parentheses.
(2*x)-(2*4) and (7*x)+(7*2)
then simplify
2x-8 and 7x+14
Next, we add the like terms together, using the commutative property.
We then factor the expression
to get the simplified form.

Hi!
Your answer is the 1st one, <u>36 inches of ribbon.</u>
The question states this is a square picture frame. That means that all the side lengths are the same.
We are given a side length of 6 inches.
In order to find the area of a square, we multiply the length and the width together, but since they are the same value, we are just doing 6 x 6.
Answer:
1. 30
2. 150
Step-by-step explanation:
Lets assume tan(x) = u
Now we solve for 'u'
add 1 on both sides
, divide both sides by 3
Take square root on both sides
We replace tan(x) for 'u'
x = 30 because in first quadrant
x = 30 (tan is positive in first quadrant)
x = 150 because in second quadrant
tan is negative in second quadrant
