Answer:per pound would cost 2.50 and for nine pounds it would cost 22 dollars and 50 cent
Step-by-step explanation:
750 divided by 3=250 just add your point were before five and 7.50 plus 7.50 equals 15 plus 7.50 equals 22.50
Answer:
4x^2 + 4x -2
Step-by-step explanation:
Use FOIL to solve (x+2) (x+2)
4(x^2 + 4x +4) - 6
4x^2 + 4x -2
65x^2 + 212x - 133
you have to use the quadratic formula
x=( -b +/- √b²-4ac) / 2a
a is 65
b is 212
c is 133
because the first value is squared you will have 2 answers
x= 7/13
x= - 19/5
<h3>
Answer: 24 (choice C)</h3>
Assuming M is a midpoint of KW, this means that WM and KM are congruent
WM = KM
x+3 = 2(x-3) ... substitution
x+3 = 2x-6
2x-6 = x+3
2x-6-x = x+3-x .... subtract x from both sides
x-6 = 3
x-6+6 = 3+6 ... add 6 to both sides
x = 9
Use x = 9 to find the length of WM
WM = x+3 = 9+3 = 12
Which can be used to find the length of KM as well
KM = 2(x-3) = 2(9-3) = 2(6) = 12
both lengths are the same (12) as expected
This makes WK to be
WK = WM + KM
WK = 12 + 12
WK = 24
B) 2/5
I think, if a and b are the same (coz then they would both equal 0.2)
