Answer:
x1=(7-√65)/2
x2=(7+√65)/2
Step-by-step explanation:
x^2=7x+4
x^2-7x-4=0
D=(-7)^2-4*1*(-4)=49+16=65
x1=(-(-7)-√D)/(2*1)=(7-√65)/2
x2=(-(-7)+√D)/(2*1)=(7+√65)/2

Answer:
Hence the values for x and y are 10 and 17 units respectively.
Step-by-step explanation:
Given: ABCD is parallelogram.
AB=4y-3
BC=42
DC=37
AD=3x-9
To Find:
Values for x and y
Solution:
As ABCD is parallelogram with AD and BC as parallel sides.
<em>So a parallelogram has opposite sides parallel and equal in length.</em>
<em>Hence AB || DC and AB=DC</em>
<em>AD|| BC and AD=BC</em>
So,
4y-3=37 and
3x-9=42
Hence,
4y=37+3=40
y=10
and
3x=51
x=17
Answer: x=75
Explanation:
x+10+x+20=180
combine like terms
2x+30=180
subtract 30 from each side
2x=150
divide each side by 2
x=75
