Answer:
C) 64x2 + 40x + 25
Step-by-step explanation:
we are given
we can also write as
we can use factor formula
we can compare and find 'a' and 'b'
a=8x
b=5
now, we can simplify it
so, (64x^2+40x+25) factor matches
Answer:
Step-by-step explanation:
<u>Equation of the line</u>
The slope-intercept form of a line is given by:
Being:
m = the slope of the line
b = the y-intercept
We can also use the point-slope form of the line:
Being:
(h,k) = A point that belongs to the line
Two lines of slopes m1 and m2 are perpendicular if:
We are given the line:
Whose slope is m1=-2
Thus, the perpendicular line has a slope of:
The required line contains the point (-8,1), thus the equation is:
Removing the parentheses:
Adding 1:

Step-by-step explanation:
m<5 = 60 (<5 & 60deg < are vertical)
m<6 = 120 (<s 5 and 6 are a linear pair)
m<9 = 120 (<s 6 and 9 are vertical)
m<4 = 80 (<s 4 and 80 deg < are vertical)
m<7 = 100 (<7 and 80 deg < are linear pair)
m<10 = 100 (<s 7 and 10 are vertical <s)
m<8 = 60 (<s 5 and 8 are corresp <s)
m<3 = 80 (80 deg <3 are corresp <s)
m<2 = 40 (80 + 60 + m<2 = 180)
m<1 = 60 (<s 1 & 5 are alt int <s)
