3(x+5)=39
3 * x + 3 * 5 = 39
3x + 15 = 39
3x = 39 - 15
3x= 24
x = 8
Answer:
(2x-9)(2x+9)
Step-by-step explanation:
This is a difference of squares because it can be written as (2x)^2-9^2
The formula for factoring a difference of squares is a^2-b^2=(a-b)(a+b)
So replace a with 2x and b with 9 giving us
4x^2-81=(2x-9)(2x+9)
Answer: 22.2
Step-by-step explanation: You have to add 97, 3, 0, 4, 7 and then then divide the total by how many numbers you added. So for this you would divide the total by 5
Point A: (-17+5)÷2=-6
Point B: (-6+0)÷2=-3
Hope my answer helped u :)
X = 33 ~ Interior Angles Theorem
y = 38 ~ 33 + 109 + y = 180
142 + y = 180
__________
-142 -142
y = 38
z = 109 ~ y - Interior Angles Theorem
x - Interior Angles Theorem
33+38+z = 180
71 + z = 180
_________
-71 -71
z = 109
