3/4-4z+5/4z-1/2+1/2z
(simplify fractions by taking away)3/4-1/2=1/4
(simplify again but only fraction with a denominator of z)5/4z+1/2z=7/4z
so its 1/4+7/4z-4z
OR
I don't know if you're supposed to change by taking away 4z which is the same as 1/4z.
if so then
7/4z(previous calculation but you can use the beggining fractions if you want just add all 3 fractions with z as a denominator)-1/4z=6/4z
so its 1/4+6/4z
I don't know the others sorry
The major arc DGF and the minor arc FD both make up the circle, so their measures should add to 360°.
(arc DGF) + 153° = 360°
arc DGF = 207°
Answer:
0.05(2x +4) +0.25x =2.65
Step-by-step explanation:
The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.
SA of cube =6s²=6(9²)=486
lateral area of cylinder (area of height around tube; also don't need to include area of circle as it is part of the cubes SA)= 2(3.14)rh=6.28(3)(4)= 75.36
add together 561.36<span />
L(-8,3),K(4,1) and M(-1,-4)
Hopes this helps.
