Answer:
8
Step-by-step explanation:
Expression:
(-B)2
Let's substitute the value of B into this expression:
B = -4
(-B)2
[-(-4)]2
Notice how there are two negative signs int this expression:
[-(-4)]2
Well, there is an invisible 1 behind the first negative sign.
[-(-4)]2
[-1(-4)]2
All we have to do now is multiply:
[-1(-4)]2
(4)2
(4)2
= 8
Therefore, the value of the expression is 8.
Answer:
149.45 cm²
Step-by-step explanation:
Surface area of pyramid = ½Pl + BA
Perimeter of the base (P) = 7 + 7 + 7 = 21 cm
Slant height (l) = 12.2 cm
Area of base (BA) = ½*bh = ½*7*6.1 = 21.35 cm²
Plug in the values
Surface area = ½*21*12.2 + 21.35 = 149.45 cm²
You are adding 1 to the numerator, which means that the next numerator in the sequence is going to be 5. You are multiplying the denominator by 3, so it means that the next denominator in the sequence is going to be 162.
The answer is 5/162.
