Answer:
$337.05
Step-by-step explanation:
450 x (1- 0.3)= $315
$315 x (1+0.07)= $337.05
Step-by-step explanation:
base is 12, hypotenuse is 20
so X² is h²-b²
so X=16
Answer:
Step-by-step explanation:
MH is the diameter and it divides the circle in half.
MXH is the arc between the endpoints of the diameter, therefore is semicircle.
Correct choice is C
Answer: X = 10.20240940...
Step-by-step explanation:
x(2x + 9) = 2x^2 + 9x
2x^2 + 9x = 300
- 300 ON BOTH SIDES
2x^2 + 9x - 300 = 0
SOLVE USING THE QUADRATIC FORMULA
x = -b +/- all root (b)^2 - 4(a)(c) All over 2(a)
When all the values are plugged in:
When using "+" in the equation you should get:
x = 10.20240940…
When using "-" in the equation you should get:
x = −14.70240940…
Now.. you CANNOT have a negative length, so you cross of the negative value leaving you one value for x which is 10.20240940...
YOUR ANSWER IS: x = 10.20240940...
It can't be a whole number. It can be 1.5, or 1 1/2.
