19 yards divided by 2.5 minutes.
=19/2.5
= 7.6 yards/minute
Answer:
Surface area = 6l^2
Volume = l^3
If total surface area increased by 2, then the length increased by 
Volume then is increased by (
l)^3 = 2
l^3
1 :2 
Which is not an option in the question so this question clearly has a problem.
First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.
Second of all, if the answer is 8:1 the question should be "If <u>each sides</u> of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.
Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled <u>by doubling the height and without changing the length and width</u>" But, then the the shape would no longer be a cube.
Who even wrote this garbage question what.
Step-by-step explanation:
so first you combine like terms , 3x-x-4=4 turns into 4x-4=4 then u add 4 to both sides [inverse operations]
4x-4=4
+4 +4
--------------
4x= 8
----------
4. 4
×=2
then u use inverse operations. agian and divide 4 into 8 and you get 2 !! x = 2
The legs are 12 cm each, so the hypotenuse is√(144+144)=12√2☺☺☺☺
It depends on the line or parabola that you are talking about, more information would be needed to answer this correctly.
