[x^3/(16+8)]-2
It says the quotient, dividing, of 'a number', which means a variable or unknown number, cubed, which means to the 3rd power, and 16 increased by 8 (which is 16+ 8) and at the beginning it says 2 less than which means -2.
Answer:
1) 18 inches
Step-by-step explanation:
By the Midsegment Theorem: A midsegment connecting two sides of a triangle is parallel to the third side and is half as long the third side.
ans: 36/2 = 18
A would be the correct answer for this q
Angle A and angle B are congruent, because they are on a line, and if the middle angle is in the middle, then the two outer angles would be congruent.
Hope this helps! :)
Answer:
-499,485.
Step-by-step explanation:
We can transform this to an arithmetic series by working it out in pairs:
6^2 - 7^2 = (6-7)(6+7) = -13
8^2 - 9^2 = (8-9)*8+9) = -17
10^2 - 11^2 = -1 * 21 = -21 and so on
The common difference is -4.
The number of terms in this series is (998 - 6) / 2 + 1
= 992/2 + 1 = 497.
Sum of n terms of an A.S:
= n/2 [2a1 + (n - 1)d
Here a1 = -13, n = 497, d = -4:
Sum = (497/2)[-26 - 4(497-1)]
= 497/2 * -2010
= -499,485.
