Multiply x<span> and </span>3
<span>Multiply x and 1</span>
<span>The x just gets copied along.</span>
<span>The answer is x</span>
x
<span>3*x evaluates to 3x</span>
Because of the minus sign
<span>3x becomes - 3x</span>
<span>The answer is -3x</span>
<span>Multiply y and 2</span>
<span>Multiply y and 1</span>
<span>The y just gets copied along.</span>
<span>The answer is y</span>
y
<span>2*y evaluates to 2y</span>
<span>-3*x-2*y evaluates to -3x-2y</span>
<span>The answer is -3x-2y-2</span>
<span>-3*x-2*y-2 evaluates to <span>-3x-2y-2</span></span>
<span><span>so the first one is right</span></span>

Answer:
A. 10
Step-by-step explanation:
Based on the midsegment theorem, thus:
2x + 7 = ½(7x - 16)
Multiply both sides by 2
2(2x + 7) = 7x - 16
4x + 14 = 7x - 16
Combine like terms
4x - 7x = -14 - 16
-3x = -30
Divide both sides by -3
x = 10
A = 6
tn = a + (n - 1)d
t4 = 6 + 3d = 12
3d = 12 - 6 = 6
d = 6/3 = 2
f(n + 1) = f(n) + 2
Answer:
D
Step-by-step explanation:
(8x)² is the area of a square with a side length 8x,
because we want to find out how much space is inside a square that has two dimensions 8x length and 8x width.
