to factor it the answer is (x+1)(x+1)
to simplify it the answer is x2+2x+1
idk if this helped or not but here you go
3:6,9,12,15,18
4:8,12,16,20,24
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
The area of the triangle with the coordinate of the vertice will be 6 square units.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
Triangle RST, with vertices R(5,-9), S(9,-5), and T(7,-4), is drawn on the coordinate grid below.
Then the area of the triangle will be
Area = 1/2 [(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)]
Area = 1/2 [{5 x -5 + 9 x -4 + 7 x -9} - {-9 x 9 + -5 x 7 + -4 x 5}]
Area = 1/2 [{-124} - {-136}]
Area = 1/2 [ -124 + 136]
Area = 1/2 x 12
Area = 6 square units

Answer:
12 pounds
Step-by-step explanation:
27/9=3, so each book weighs 3 pounds
Chelsea takes 2 books, or 6 pounds
3 books, or 9 pounds, go in the locker
9+6=15
27-15=12, so his backpack weighs 12 pounds
