{c}^{2} - 64 = 0
This can also be represented as:
{c}^{2} - {8}^{2} = 0
Using difference of two squares;
(c - 8)(c + 8) = 0
c - 8 = 0 \: or \: c + 8 = 0 \\ \\ c = 8 \: or \: c = - 8



Hope I helped? ☺️

Triangles and algebra
Elanso [62]

Hello from MrBillDoesMath!

Answer:

x = 10


Discussion:

A plane triangle contains 180 degrees. Adding the angles in the triangle shown in  #8 gives

(4x + 7) + (3x + 13) + 90 = 180


Note the "right angle" shown in the triangle has been replaced by its 90 degree equivalent in the above equation.

Combining like terms gives


( 4x + 3x) + (7 + 13) + 90 = 180

7x + 20 + 90 = 180 =>                      (subtract 90 from each side)

7x + 20 + 90 - 90 = 180 - 90 = 90  =>

7x +20 = 90  =>                                (subtract 20 from each side)

7x + 20 -20 = 90 -20 =>

7x = 70 =>

x 70/7 =10.



Thank you,

MrB

A line intersects the point (3,-4) and has the slope of 17. What is the slope-intercept equation for this line
Softa [21]

Answer:

y = 17x - 55

Step-by-step explanation:

Convert the coordinates in point-slope form:

y + 4 = 17(x -3)

y + 4 = 17x - 51

Subtract 4 in both sides:

y = 17x - 55

Thanks!
