5y^2-2y-2 = 0
y = 1/5+ √11/5 or 1/5 - √11/5
Given:
A figure.
To find:
The values of x and y.
Solution:
We know that, in a right angled triangle,



Multiply both sides by 16.


And,



Multiply both sides by 16.


Therefore, the missing side lengths are
and
.
3x+4=28 because 3 times an unknown number was mentioned first and mentioned together so they will be together, increased by 4 is +4 and comes after, the result of is the same as equals so you put the equals sign and whatever number they gave after.
Well,
if 10 of the questions were worth 5pts. that would equal =50
and if 5 were worth 10pts. that would equal= 50
50 + 50 = 100pys.
The value of x is -9 and 3.Option D.
Step-by-step explanation:
Given,

To find the value of x.
We will apply middle term factor formula.
The given equation can be written as,

or,
+(9-3)x-27 = 0
or, x²+9x-3x-27= 0
or, x(x+9)-3(x+9)=0
or, (x+9)(x-3) = 0
So, x = -9 and x = 3
Hence,
The correct option is Option D.
