Answer:
4.2 pints
Step-by-step explanation:
3.5 × 1.2 = 4.2
Answer: 4.2 pints
Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:

Simplifying the integrand gives us:

Next, by hint 2, we observe that:

So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
Answer:
x > 2
Step-by-step explanation:
y < 4x +3
y > -2x - 9
-2x -9 < 4x +3
-6x < -12
IN CASES WHERE YOU DIVIDE A NEGATIVE NUMBER,DON'T FORGET TO CHANGE THE SIGN !!!
x > 2
These triangles are either 45 45 90 triangles or 30 60 90 triangles
For the 45 45 90 triangles the smaller sides are
s and the large one is s times the square root of two
For 30 60 90 the smallest side is s the hypotenuse is 2s and the last one is s root 3
For example 1. X is 7 the hypotenuse is 14
The sides on 2 are 6 Times Square root of 2
3. The sides are 3 each
