I would substitute y = x^2
4y^2 -21y+20=0
Answer:
Step-by-step explanation:
Try to say it and then write it out. I hope this helps.
Answer is D - square root of 98
Reason
Using Pythagorean theory to first solve for base diagonal with known legs 5 and 3.
a^2 + b^2 = c^2
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
Take square root of both sides
5.8 = c
Now find the answer for the diagonal
By using the same formula with known legs 5.8 and 8
5.8^2 + 8^2 = c^2
33.6 + 64 = c^2
97.6 = c^2. Round up to 98
Answer is square root of 98
Answer:
Y=2x+1
1 is the y and the 2 is the x value since every 2 blocks down and 1 over it will hit a corner or edge of box. Hopefully this helps
the answer is at the number @ 5
