Equation~ 5b + (2b - 4) + (3b -6)= 180.
Answer:
There is exactly 1 solution and it is a double root.
Step-by-step explanation:
To find this, factor the equation and solve.
x^2 + 10x - 25 = 0
(x - 5)(x - 5) = 0
Now that we have this factored, we can set each parenthesis equal to 0 and solve separately.
x - 5 = 0
x = 5
x - 5 = 0
x = 5
Because there are two of the exact same answer, we know it to be a double root.
Answer:
Try 8.91
Step-by-step explanation:
6.84+4.19=11.03-2.12=8.91
Answer:
z=1
Step-by-step explanation:
8(z+3)=32
Multiply 8 into the parenthesis.
8z+24=32
Subtract 24 both sides.
8z=8
Divide 8 both sides.
z=1
