Answer:
9x+2
Step-by-step explanation:
It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.
(2x+2)+(3x+1)+(4x-1)
2x+2+3x+1+4x-1
Combine like terms.
2x+3x+4x=9x
2+1-1=2
Left with 9x+2 as your perimeter binomial.
Answer:
C
Step-by-step explanation:
Answer:
It has no real solution.
Step-by-step explanation:
6p^2 − 7p + 5 = 0
For this equation: a = 6, b = -7, c = 5
6p^2+ −7p + 5 = 0
Step 1: Use quadratic formula with a=6, b=-7, c=5.
p = -b ± √b^2 - 4ac/2a
p = -(-7) ± √(-7)^2 - 4(6)(5)/2(6)
p = 7 ± √-71/12
Answer:
How many centimeters of string does she need?
30 * 30 cm = 900 cm
If the total cost of the string was $4.41, how much did she spend per meter?
