An equivalent fraction for 2/9 is 4/18
and for 3/7 you have 6/14
I got it by multiplying both fractions by 2<span />
I think this is the answer you are looking for
You would be able to cut 144 pieces of wire from the spool because 270/1 7/8 (or 1.875) equals 144
If angle 10 and 15 are congruent ( the same) that would mean lines a and b would need to be parallel with each other because that have the same angles.
The answer ic C.
Remark
What value of k will make the entire polynomial = 0 when k is meant to be a factor? In brief, solve the polynomial when f(-3) is substituted into the right hand side.
f(x) = 2x3+x2+kx+18
f(-3) = 2x3+x2+kx+18
f(-3) = 2(-3)^3 + (-3)^2 - 3k + 18 = 0
-54 + 9 - 3k + 18 = 0
-54 + 9 + 18 - 3k = 0
-27 - 3k = 0
- 3k = 27
k = 27/ - 3 = - 9
Answer
k = -9
Check
2x^3 + x^2 - 9x + 18 = 0
2(-3)^3 + (-3^2) - 9(-3) + 18 = 0
-54 + 9 + 27 + 18 = 0 Just as it should be.
