The answer to your problem is x=5
Energy in the form of HEAT
How many ounces are there
Answer:
a. 6x^2+x+0.7
b. 5x^2-2x-2
Step-by-step explanation:
a. 6x^2+2x-3-x+4.7-1
Simplest form is when all the terms are ordered by power and like terms are combined. I'm assuming the first term is 6x^2 because 6x2 seems a bit odd to me. When you combine like terms and reorder everything, you get
6x^2+x+0.7
b. 6x^2+2x-3-x^2-4x+1
The first thing I did was distribute the negative. Next, you just repeat the same steps. Combine like terms and reorder. The final result is:
5x^2-2x-2
I want to say 81°
Here's how I found that:
The angle 105° is on a straight line showing the outer obtuse angle. A straight line is 180°.
180-105=75.
Therefore that inner angle of the 105° is 75°.
We are also given the top angle of 24°.
All 3 angles of a triangle should add up to 180. So, we get the 75+24=99
180-99=81
Last angle should be 81°
