Find the value of (3 + 4)2

elena55 [62]

Answer:

Step-by-step explanation:

We solve this by using 2 to open the bracket

(3+4)2 is the same as 2(3+4)

2(3)+2(4)

=6+8

=14

(3+4)2 is the same as 2(3+4)

So we can solve the one inside the bracket first

=2(7)=14

Triangle BCD is isosceles and line Bc is congruent to line BD. What is the measure of arc BC?

Leokris [45]

Since arc CD is 100 degrees, the rest of the circle must be 260 degrees. Since the rest of the circle is made up of two equal arcs, then arc BC must be half of 260 degrees. Thus, the answer is 130 degrees, C.

I didn't understand this to be honest I thought I had to find what jm and lm were together and then subtract from the whole tota

prisoha [69]

Answer:

The correct answer is 3x-2

Step-by-step explanation:

It gives you the expression for JM and LM, and it asks for JL. Therefore, if you take away LM from JM, you are left with JL. You must subtract 2x-6 from 5x-8.

∴5x-8-(2x-6)

Do not forget to distribute the negative since you are subtracting, so instead of subtracting 6 from 8, you will be adding 6 to 8 because two negatives make a positive.
