Answer: r = -5/18
Step-by-step explanation: You solve -3(1+6r)+12=14
-3-18r+12=14 (When distributed)
-18r+9=14
-18r=5
r=-5/18
We are given with
<span>mXZ = 140∘
mXSZ = 220∘
and YX and YZ are tangents to circle A at X and Z.
According to the theorems on circles, the angles formed by the intersection of the two tangents is half the difference between of the measure of the arcs subtended by the tangents. So,
</span>∠XYZ = (220 - 140) /2 = 40∘<span />
I think the first one is a simple as it gets
for the second one it could be simplified to 6x^6-4 because u combine the x terms and distribute the power
Answer:
180m-40
Step-by-step explanation:
60m-15(4-8m)+20
= 60m-60+120m+20
= 180m-40
