Answer:
x = -2 or x = 1/3 thus: B & C
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + 7 x - 2 = 2 x - x^2
Subtract 2 x - x^2 from both sides:
3 x^2 + 5 x - 2 = 0
The left hand side factors into a product with two terms:
(x + 2) (3 x - 1) = 0
Split into two equations:
x + 2 = 0 or 3 x - 1 = 0
Subtract 2 from both sides:
x = -2 or 3 x - 1 = 0
Add 1 to both sides:
x = -2 or 3 x = 1
Divide both sides by 3:
Answer: x = -2 or x = 1/3
Answer:
3630 dollars
Step-by-step explanation:
First, we need to find the area of the the room floor. To do this, we need to do 12 × 10 because 12 is the length and 10 is the width. 12 × 10 is 120. We also know that each square yard of carpet costs $30.25. We now have to multiply 120 × 30.25 because the room is 120 square feet large. 120 × 30.25 = 3630, so the carpet costs $3630.
Answer:
A. 32
Step-by-Step Explanation:
∠QRP = 32
if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
∠QRP ∠QPR
Substitute ∠QPR 32° into ∠QRP : ∠QRP 32°
Answer:
y-2=4/3(x-2)
Step-by-step explanation:
Pick one coordinate and then plug the x value and the by value into the formula and then to find the slope and count up 4 and to the right 3.
Step-by-step explanation:
n-8≤17
add 8 on both sides to isolate the variable.
n is less than or equal to 25
