Remember to follow PEMDAS, and to only combine terms with like variables.
First, distribute the 2 to all terms within the parenthesis:
2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t
3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.

Answer:
x=7
Step-by-step explanation:
Add 10 to both sides to isolate x.
4x=28
x=7
Answer:
The unknown is 100
Step-by-step explanation:
A straight line is 180 degrees
We have two angles x, and 80
x+80 = 180
x = 180-80
x= 100
Hello,
The formula for finding the area of a circular region is:

then:

With the two radius it is formed an isosceles triangle, so, we must obtain its area, but first we obtain the height and the base.

Now we can find its area:
![A_{2}=2* \frac{b*h}{2} \\ \\ A_{2}= [r*sen(40)][r*cos(40)]\\ \\A_{2}= r^{2}*sen(40)*cos(40)](https://tex.z-dn.net/?f=A_%7B2%7D%3D2%2A%20%5Cfrac%7Bb%2Ah%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20A_%7B2%7D%3D%20%5Br%2Asen%2840%29%5D%5Br%2Acos%2840%29%5D%5C%5C%20%20%5C%5CA_%7B2%7D%3D%20r%5E%7B2%7D%2Asen%2840%29%2Acos%2840%29)
The subtraction of the two areas is 100cm^2, then:
Answer: r= 1.59cm
Answer:
150
Step-by-step explanation:
A=B*H/2
A=15*20/2
A=300/2
A=150
Ignore the hypotenuse btw
