2k^2+3k-13=k^2+15
subtract k^2 -15 from each side
k^2 +3k -28=0
(k+7)(k-4)=0
k=-7 k=4
Answer: k= -7,4

Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
Answer:
220 miles
Step-by-step explanation:
Joe got $301 for an overnight trip.
As the employees get $125 for lodging. The lodging expense will be subtracted from the total amount to get the amount for the miles he drove.
So,
Expense by company for miles driver = 301 - 125 = $176
So, Joe received $176 for miles driven
Now,
amount for one mile = $0.80
Miles driven in $176 = 176/0.80 = 220 miles
Joe drove 220 miles ..
