General form of a linear equation is ax+by+c=0 where a,b, and c are three real numbers.
So, we can shift all the terms in one side of the equation. Hence, first step is to remove y from the left side. So, subtract y from each sides.
y-y=3x+2-y
0= 3x - y +2 (By simplifying)
So, the general form of the given equation is 3x-y+2=0.
Side a can be broken into to rectangles having areas:
(12-8)*4 and 8*12 so the area of side A is
A=16+96
A=112cm^2
Answer:
$11,170
Step-by-step explanation:
First you convert the percentage to decimal form out of 100 (which you divide)
3.9%/100 = 0.039
A = P(1 + rt)
A = 10000(1 + 0.039 * 3) ( * = multiplication)
I = $11,170 - 10,000 = $1,170
Which you should get $1,170.00 or $1,170 (which is pretty much the same thing)
Hope this helps!
Lets x = width
height = 2x - 4
A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7
so width = 9
height = 2(9) - 4 = 18 - 4 = 14
answer
width = 9 in
height = 14 in
Your answer would be 54 degrees since 90+36=126 so then you subtract 126 from 180 and get 54
