Answer:
x = 0 or x = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
17=x2+8x+17
Step 2: Subtract x^2+8x+17 from both sides.
17−(x2+8x+17)=x2+8x+17−(x2+8x+17)
−x2−8x=0
Step 3: Factor left side of the equation.
(−x)(x+8)=0
Step 4: Set factors equal to 0.
−x=0 or x+8=0
x=0 or x=−8
Answer:
15
Step-by-step explanation:
Set up a proportion.
6/10 = x / 25 Cross Multiply
10*x = 6 * 25 Combine the right.
10x = 150 Divide both sides by 10
10x / 10 = 150/10 Do the division
x=15
She should complete 15 baskets
(8c)^2+7c
(8c)^2=64c^2
so that..
64c^2+7c
factor out c
c(64c+7)
Set up a proportion, then solve.
5/3 = 315/x
Cross multiply
5*x = 5x
3*315 = 945
5x = 945
5x/5 = 945/5
x= 945/5
x= 189
Final answer: The riders are 189
