Answer:
35
Step-by-step explanation:
Since the sequence is so short, you can simply add the terms. It is convenient to do them pairwise, working inward from the first+last:
(-4+14) +(-1+11) +(2+8) +5
= 10 +10 +10 +5
= 35
__
Or, you can find the average term as the average of the first and last terms:
average term = (-4+14)/2 = 5
Then the sum is the product of this and the number of terms:
sum = (number of terms)×(average term) = 7 × 5 = 35

Answer:
164.7 in2
Step-by-step explanation:
Solve for surface area
Shape: Pyramid
Formula: L*W*H
A≈167.13 round to the nearest ten = 164.7 in2
The correct answer to this question is 164.7 in2
So A is the correct answer

Xy = 8
x + y = 6
x + y = 6
x - x + y = -x + 6
y = -x + 6
xy = 8
x(-x + 6) = 8
x(-x) + x(6) = 8
-x² + 6x = 8
-x² + 6x - 8 = 0
-1(x²) - 1(-6x) - 1(8) = 0
-1(x² - 6x + 8) = 0
-1 -1
x² - 6x + 8 = 0
x² - 4x - 2x + 8 = 0
x(x) - x(4) - 2(x) + 2(4) = 0
x(x - 4) - 2(x - 4) = 0
(x - 2)(x - 4) = 0
x - 2 = 0 or x - 4 = 0
+ 2 + 2 + 4 + 4
x = 2 or x = 4
x + y = 6
2 + y = 6
- 2 - 2
y = 4
(x, y) = (2, 4)
or
x + y = 6
4 + y = 6
- 4 - 4
y = 2
(x, y) = (4, 2)
The two numbers that add up to 6 and multiply to 8 are 4 and 2.
