First you connect the lines by making a triangle. Then you get the value of one side (4) and you square it. (4 squared= 16). You also do the same with another side (3 squared= 9). And then you add them and square root the number to get the answer. (5)

2 (y+6) + 6 (y+6) Expand and simplify

san4es73 [151]

Hi there! The answer is 8y + 48.

$2(y + 6) + 6(y + 6)$
First work out the parenthesis.

$2y + 12 + 6y + 36$
Rewrite the expression in order to collect the terms.

$2y + 6y + 12 + 36$
Next up, collect the terms.

$8y + 48$
Now we've found our answer.

Lemur [1.5K]

Answer:

6 minutes

Step-by-step explanation:

Connor drives from the village to Belfast at an average speed of 40mph.

The distance covered is 20 miles.

Time = distance/ speed

Time = 20/40

Time = 0.5 hours

Time = 30 minutes.

Kelly drives from the village to Belfast at an average speed of 50mph.

Time = distance/speed

Time = 20/50

Time = 0.4 hours

Time = 24 minutes

It will take Conor 30 - 24 = 6 minutes longer than Kelly
