Answer:
Step-by-step explanation:
G=30t+40, C=20t+60, C=G
30t+40=20t+60, subtract 40 from each side
30t=20t+20, subtract 20t from each side
10t=20, divide each side by 10
t=2
So both garages charge the same fot two hours of work.
Answer: <em>D) </em><u><em>He cannot construct a triangle</em></u>
Step-by-step explanation:
For a triangle to be possible <u>the largest side must be less than the sum of other two sides .</u>
In the given question largest side is 23 while other two sides are 8 and 14
Therefore for triangle to be possible 23 should be less than (8+14) but 23 > (8+14) .
Thus he can not construct a triangle using the given sides.
Hence correct option is <u><em>D)He cannot construct a triangle.</em></u>
Answer:
A
Step-by-step explanation
0 -4 -1 1 2
theyre also all in bold correct order as should be
f(4)=9*4-2 =34 & g(4)= -2*4 =-8 then,
f(4)- g(4) = 34+8= 42
