2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
Answer: three n minus thirty-five equals seventy-nine
Step-by-step explanation:
Answer: Length = 11
Width = 9
Step-by-step explanation:
Let x represent the unknown length.
Let x - 2 represent the unknown width.
The perimeter is equal to 2 times x + (x -2)
Equation:
2 (x + (x - 2)) = 40
x + (x - 2) = 40/2
x + x - 2 = 20
2x - 2 = 20
2x -2 + 2 = 20 + 2
The length is: 2x = 22 -> x = 22/2 -> x = 11
The width is: x - 2 = 9
Answer:
angle N is 79, angle K is 22, angle P is 81, angle D is 76
Step-by-step explanation:
all of the angles should add up to 180 degrees so add the two angles you have and subtract them from 180
3(a-b) and 3a-3b. Equivalent
2a(2+b) and 4ab. Not equivalent
