Answer:
d=13
Step-by-step explanation:
step 1) combine like terms
8d-3d-12=53
5d-12=53
isolate d
5d-12+12=53+12
5d=65
d=13
(5 1/4 in)(12 1/2 in)(4 in)
(21/4)(25/2)4=262.5 in^3
Answer:
x=12
Step-by-step explanation:
Slope-intercept form is:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
(there is probably another way to do this, but I will be doing it this way)
Isolate the "y" in the equation
3x + 4y = 12 Subtract 3x on both sides
4y = 12 - 3x Divide 4 on both sides
or
The slope is -3/4
For lines to be parallel, they have to have the SAME slope. The given line's slope is -3/4, so the slope of the parallel line is also 
<u>x^2-10x+25</u>
=x^2-5x-5x+25
x(x-5)-5(x-5)
<u>=</u><u>(</u><u>x-5)</u><u>(</u><u>x-5)</u>
<u>x=</u><u>5</u><u> </u><u>,</u><u> </u><u>x=</u><u>5</u><u> </u>
