Answer: 8x+12
Step-by-step explanation:
perimeter equals (x+4) + (3x+2) + (x+4) + (3x+2) = x+4 + 3x+2 + x+4 + 3x+2 = 8x+12
Answer:
4x.
Step-by-step explanation:
If the scale factor is 2 then the area factor is 2^2 = 4.
So the area of the new triangle is 4*x.

<h2>
The manager's claim is likely to be true.</h2>
Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct
