Answer:
1. 2(a^2 + 3a + 9)
2. 5(x^2 - 1)
3. 3(t + 8)(t - 2)
4. n(4 - n)
Step-by-step explanation:
For 1, you can only factor out the constant from each.
For 2, you can also only factor out the constant, but remember that you include the 1 when dividing 5 by 5.
For 3, you can factor out the constant and the variables.
For 4, you can only factor out the variable.
The correct answer is 36pi.
<span>The length of each side of pentagonal church window with the perimeter of 60 inches is C. 12 inches. The perimeter (P) of a pentagon is the sum of its side lengths (s). Since pentagon has 5 sides, the perimeter of the pentagon is: P = 5s. If we know that the perimeter is 60 inches, the side length will be: 60 in = 5s. s = 60 in / 5. s = 12 in. The length of the side of the window is 12 inches.</span><span />
Answer:
x²+1 is the second
Step-by-step explanation:
2x+24=40°
4x+43=75°
x²+1=65°
(2x+24) + (4x +43) + (x²+1)=180
x²+6x+68=180
x1=-14
x2=8
since there's no negative angle, we'll use x=8
The answer is B.
Since the fractions are the same (5 )you leave it as it is so you just multiply the powers and then add the power
