Answer:
x=2
Step-by-step explanation:
We are given that the length of the line segment AC is 39. We are also given the length segment of AB = 9x+7 and the line segment BC is equivalent to -3x+20.
We also know based off the diagram that AC = AB + BC. We can use substitution to set up an equation:
AB+BC=AC
9x+7-3x+20=39
Combine like terms
6x+27=39
Subtract 27 from both sides
6x=12
Divide both sides by 6 to isolate x
x=2
Answer:
These two results are identical.
Step-by-step explanation:
Before we can compare these two expressions we need to perform the indicated multiplication.
The first expression is 9c + 2.
After the multiplication indicated, the second expression is 9c + 2.
These two results are identical. Yes, the two expressions ere equal.
Answer:
Step-by-step explanation:
10x^2-10x-6 + x+6
= 10x^2- 9x
Well…… I’m not sure. Sorry bud
Looking at the question, we can see we have 5 different numbers that can go in any order.
<u>5</u> * <u>4</u> * <u>3</u>
The above is basically saying there are 5 different numbers that can be multiplied by 4 other numbers. Those 2 can be multiplied by 3 different ones, leaving us with a 3 digit positive integer.
5 * 4* 3 = 60
