Answer:
The discriminant is 40
Step-by-step explanation:
First, rewrite the equation as 
so that the equation is in the form of 
. Thus, the discriminant is 
. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.
Answer:
C = 31
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
First, find the area of the shelf if it were a full circle.
the formula for the area of a circle is a=pi(r squared)
a=pi (10.5 squared)
a=pi x 110.25
a=3.14 x 110.25
a=346.185
now, you have to divide that area by 4 to get the area of the 1/4 circle
346.185/4=86.55
Answer:
75
Step-by-step explanation:
75 × 75 = 5625
75² = 5625
X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)
