For A B and C, you just plug in the given number
A
B
C
And for D, you set the equation to 26 and solve for n
I had to use x instead of n, but for D n=7. :)
Since every side of a square is the same length, and the formula to find the area is bh you would just do 2.75²
2.75×2.75=7.5625≈7.56
the answer is the area of the square is approximately 7.56u²
Answer:0.9 * (36.2/10.5) = 3.1 in
Step-by-step explanation:
I got an A <3
Divide 22 by 2 sevenths; 22 / (2/7) = 77
Answer:
-1+√6
-1-√6
Step-by-step explanation:
x²+2x-5=0
x=(-2±√(2²-4(-5)))/2=(-2±√(4+20))/2=(-2±√24)/2
x₁=(-2+√24)/2 or x₂=(-2-√24)/2
x₁=(-2+2√6)/2 or (-2-2√6)/2
x₁=-1+√6 or x₂=-1-√6
