To factor,
We need 2 numbers that multiply to get 10 and add to get -7 which is,
-2 and -5.
-2*-5 = 10
-2x + -5x = -7x
x*x=x^2
Factored - (x - 2)(x - 7)

Answer(s):
If you are asking for the equation, it's 9(x+4)=2
However, if you're asking for the value of x as well, it's -34/9
Step by Step:
1) First we must find the equation. In your question, the unknown number is x. Therefore we can know that "the sum of a number and 4" is (x+4). Since we are multiplying this sum by 9, we can put the 9 in front of this expression to multiply it--getting 9(x+4). And since we know it "is 2" we can say that 9(x+4)=2.
2) Now, we have to solve the equation, 9(x+4) = 2
3) We can start by distributing, 9x+36 = 2
4) Now let's move 36 to the right by subtracting from both sides, 9x = -34
5) To isolate x, let's divide both sides by 9, x = -34/9
6) Our fraction answer can't be simplified, so we get x = -34/9
The measure of angle A is 45 degrees
Answer:
7.5%
Step-by-step explanation:
Approximate distance = 180 miles
Actual distance = 167.5 miles
Percent error = { (approximate value - actual value) / actual value } × 100
= { (180 - 167.5) / 167.5 } × 100
= (12.5 / 167.5) × 100
= 0.075 × 100
= 7.5%
