Hello from MrBillDoesMath!
Answer:
(1/8) ( 7 + sqrt(481) )
(1/8) ( 7 - sqrt(481) )
Discussion:
The equation is equivalent to 4x^2 - 7x -27 = 0 (as 3 + 24 = 0), Using the quadratic formula:
x = ( - (-7) +\- sqrt ((-7)^2- 4*4*(-27)) )/ (2*4)
= (1/8) ( 7 +\- sqrt(49+ 432) ) =
= (1/8) ( 7 +\- sqrt(481))

Answer:
x=2
Step-by-step explanation:
5x-10=0 add 10 on both sides
+10 +10
-------------- -10-10=0
0+10=10
5x=10
5x=10 divide 5x by 5 and 10 divided by 5
--- ---
5 5
x=2 because 10 divided by 5=2
Answer:
The perimeter is 22.
Step-by-step explanation:
If you turn this shape into a rectangle, the perimeter doesn't change.
The width is given, it is 7.5. The height is BC+DE = 3.5
Then the perimeter is twice the width plus twice the height:
7.5*2 + 3.5*2 = 15+7 = 22
