Need help with 5e + 8f + (-2)e - 12f
Ivanshal [37]
You have to add your like terms. So you would add 5e + (-2)e first. That would equal 3e. Next you would add 8f + (-12)f. That would equal -4f. You final answer would be 3e - 4f.

A circle has a circumference of 3.14 units. What is the diameter of the circle?
FrozenT [24]

Answer:

d = 1

Step-by-step explanation:

d\pi = C

So I would think d = 1

Because pi = 3.14

so...

1(3.14) = C

I'm not 100% but that's what I would say.

Hope this helps!!

An isosceles triangle has base angles that each measure 39 °. Which equation can be used to fi nd t, the measure of the third an
Montano1993 [528]

Answer: 102°

Step-by-step explanation:

First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.

Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:

t + 39° + 39° = 180°

t + 78° = 180°

t = 180° - 78°

t = 102°

The third angle is 102°.
