Answer:
5) x = 5
6) x = 8
Step-by-step explanation:
5) Since RT is 40 and RS is 15, ST = RT- RS=25
Since ST also equals 5x, 5x = 25 and x = 5.
6) Since ∠CBD and ∠DBA are supplementary, they add up to , and because ∠CBD = , ∠DBA = .
Since ∠DBA - ∠DBE = ∠EBA, ∠EBA = .
Also ∠EBA = 6x + 2, so 6x + 2 = .
6x = 48, and x = 8.
x + 1 = x + 1
x - x = 1 - 1
0 = 0
Most likely B because x>1 = enlargement vs x<1 = reduction, & the x & y are doing two completely different things
3(√x+1-5)=27
divide both sides by 3
√x+1-5= 27
add 5 to both sides
√x+1=27+5
√x+1=32
take square of both sides
x+1=32
subtract 1 from each sides
x=32-1
x=31
