Answer: 3 buses
Step-by-step explanation: If 54 students fit on a bus, and 125 students are in 8th grade,
You should divide.
125 divided by 54 is 2.31...
we can't have 2.31... buses, so we say 3 buses.

No doubt thats the correct answer guys, thank me later
Answer:
Step-by-step explanation:
Remark
It's a right triangle so the Pythagorean Theorem applies. All you have to do is put the right things in the right places of the formula.
Givens
a = x
b = x + 4
c = 20
Formula and Substitution.
a^2 + b^2 = c^2
x^2 + (x + 4)^2 = 20^2
Solution
x^2 + x^2 + 8x + 16 = 20 Collect the like terms on the left.
2x^2 + 8x + 16 = 20 Subtract 20 from both sides.
2x^2 + 8x + 16 - 20 = 0
2x^2 + 8x - 4 = 0 Divide through by 2
x^2 + 4x - 2 = 0
Use the quadratic formula
a = 1
b = 4
c = - 2

From which x = (-4 +/- sqrt(24) ) / 2
x1 = (- 4 +/- sqrt(4*6) ) / 2
x1 = (- 4 +/- 2 sqrt(6) ) / 2
x1 = -2 + sqrt(6)
x2 = -2 - sqrt(6) This is an extraneous root. No line can be minus.
x1 = + 0.4495
x2 = x + 4 = 4.4495
Answer:
false, false
Step-by-step explanation:
C' is (5, 4)
A' is (5, -4)
Each side of the triangle is larger in the image, and the area is larger.
Answer: false, false
