<u>Answer:</u>
x = -3/7
<u>Step-by-step explanation:</u>
We are given the following equation for which we have to solve for x:

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

Therefore, x = -3/7.
X = 105
The circle is 360, so add the two numbers that are already present there together,. The rest two side are the same, so use 2x, x for one side, so two for two side.
85 + 65 + 2x = 360
150 + 2x = 360
2x = 210
x = 105
Answer:
B
Step-by-step explanation:
26 letters 10 numbers no repeating
P(26,2)×P(10,4)
=26×25×10×9×8×7=3276000
Well there are 52 cards in a deck. There are 13 of each kind of card. So 13/52 are diamonds
Answer: C. y=4x-7
Step-by-step explanation: 4 is the slope so it is next to x and -7 is the y intercept so -7 is after 4x.
