Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x=
or x=5
Answer:
x=
or x=5

Answer:
A. x > -1
Step-by-step explanation:
- (x - 3) < 4 (2 + x)
-x + 3 < 8 + 4x
-5x + 3 < 8
-5x < 5
x > -1
Therefore, answer choice A is the correct answer.
The answer is: " 132° " .
____________________________________
Note: m∠9 = m∠11 = m ∠16 ;
So; m∠11 + m∠16 = 132 .

Answer:
(2n+6)^2
Step-by-step explanation:
To solve this, you can use the given formula: x^2 + 2xy + y^2
In this case, 4n^2 is x^2, 24n is 2xy, and 36 is y^2. The next step is:
(2n)^2 + 2(2n)(6) + (6)^2
Since this equation fits into this formula ( x^2 + 2xy + y^2), we can do:
(2n+6)(2n+6) =
(2n+6)^2
Hence, the answer is (2n+6)^2
