Yes, what?
Answer:
<A= 65 & <B=78
Step-by-step explanation:
this is because first we must find X, so in order to do so we must add together all angle measures, then make that equal 180. So
(2x-9)+(2x+4)+x=180
2x+2x+x-9+4=180
5x-5=180
5x=180+5
5x=185
X=185/5
x=37
Then we just have to plug in the value of x into the angle measurements.
First distribute the negative
(-x+2)(x-7)
Next multiply -x by x
Then multiply 2 by x
Then multiply -x by -7
Then multiply 2 by -7
-x^2+2x+7x-14
-x^2+9x-14 is your answer
Answer:
Equations:
a + b = 19
a = b + 2
a = Money that spent Laura
b = Money that spent Laureen
then:
(b+2) + b = 19
2b + 2 = 19
2b = 19-2
2b = 17
b = 17/2
b = 8.5
a = b + 2
a = 8.5 + 2
a = 10.5
Check:
10.5 + 8.5 = 19
