Answer:
(x + 4) × (2x - 5)
Step-by-step explanation:
- Begin by writing 3x as a difference
- 2x^2 + 8x - 5x - 20
- Factor out 2x from the expression
- 2x × (x + 4) - 5x - 20
- Factor out -5 from the expression
- 2x × (x + 4) - 5 (x + 4)
- Factor out x + 4 from the expression
- (x + 4) × (2x - 5)
Hope this helps!!
The statement that is true about the equation 3(-y + 7) = 3(y + 5) + 6 is;
Statement A; The equation has one solution, y = 0
The given equation is;
3(-y + 7) = 3(y + 5) + 6
Expanding the brackets gives us;
-3y + 21 = 3y + 15 + 6
-3y + 21 = 3y + 21
Using subtraction property of equality, subtract 21 from both sides to give;
-3y = 3y
Using addition property of equality, add 3y to both sides to give;
-3y + 3y = 3y + 3y
6y = 0
Using division property of equality, divide both sides by 6 to get;
y = 0

The missing statements are;
A. The equation has one solution, y = 0.
B. The equation has one solution, y = -1.
C. The equation has no solution.
D. The equation has infinitely many solutions.
Answer:
A has the largest surface area.
Step-by-step explanation:
Surface Area of A = 2(10*3.5) + 2(10*4) + 2(4*3.5)
= 70 + 80 + 28
= 178 in^2.
For B:
Area = 2(12*3.2) + 2(12*2.8) + 2(2.8*3.2)
= 76.8 + 67.2 + 17.92
= 161.92 in^2.
Answer:
b is the aswer
