Answer:
C, D, F
Step-by-step explanation:
75-25=50
50/75=0.6666666...
0.6666666...x100=66.666...
=66.7%
Answer:
Answer choice b) 2x^4+11x^3+12x^2−10x−8
Step-by-step explanation:
(x^2+4x+2)(2x^2+3x+−4)
=(x^2)(2x^2)+(x^2)(3x)+(x^2)(−4)+(4x)(2x^2)+(4x)(3x)+(4x)(−4)+(2)(2x^2)+(2)(3x)+(2)(−4)
=2x^4+3x^3−4x^2+8x^3+12x^2−16x+4x^2+6x−8
2x^4+11x^3+12x^2−10x−8
Witch leave us with the answer choice B) 2x^4+11x^3+12x^2−10x−8
1.) You are trying to find the amount of lawns mowed at 35 hours so we'll need to make a proportion: 7/4=35/x (x is the variable you're trying to find)
2.) Cross multiply the proportion: 7/4=35/x
35*4=140
3.) Divide 140 by 7
140/7=20
4.) 35 hours would accumulate to 20 lawns.The rate would be 35:20 and unit rate 6:4
Because the distance to both chords are the same (5.70) and both chords are 90 degrees from the 5.70 line, both chords are identical.
Chord AB = 5, so chord CD is also 5.
