Answer:
(11b^2 + 7) (11b^2 - 7)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49
Answer:
D
Step-by-step explanation:
I'll it explain it as soon as it sends
20 x 4 - 100 ÷ 5
Pemdas First parenthesis then multiplica or division and the addition or subtraction. Everything from left to right
first multiplication
80 - 100 ÷ 5
Then division
80-5
then subtraction
75
Answer:
57, 57, 66
Step-by-step explanation:
This is isosceles, so angle B is the same measure as angle C, and all 3 angles add to 180.
2x+47 + 2x+47 + 3x+51 = 180
7x + 145 = 180
7x = 35
x = 5
Angles B and C are 2x + 47, so 2(5) + 47 = 57
Angle D is 3x+51, so 3(5) + 51 = 66
Answer:
(B)21+3a
Step-by-step explanation:
An expression is said to be distributive when:
![(a+b)c=a \cdot c+b \cdot c](https://tex.z-dn.net/?f=%28a%2Bb%29c%3Da%20%5Ccdot%20c%2Bb%20%5Ccdot%20c)
Given the algebraic expression: (7 + a)3
Applying the distributive property
![(7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a](https://tex.z-dn.net/?f=%287%20%2B%20a%293%20%3D%207%20%5Ccdot%203%2Ba%20%5Ccdot%203%5C%5C%3D21%2B3a)
An equivalent expression is 21+3a.
The correct option is B
