Step-by-step explanation:
x1 = -5, x2 =3 , y1 = -4 , y2=1
- formula = square foot of (x2 -x1)^2 + (y2 -y1)^2
- sqare root of (3 +5)^2 + (1 +4)^2
- square root of (8)^2 + (5)^2
- square root of 64 + 25
- square root of 89
- = 9.43
Answer:
it is 27
Step-by-step explanation:
it is asking for absolute value of 27 which means how far is that number from 0. so it would be 27.
Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
Your answer is 9x-8.
3x+4, x-10, 5x-2. If you combine the x's you get 9x. You can combine the numbers however you'd like. I chose to combine +4 and -2. That's 2. 2-10 = -8. Therefore your answer is 9x-8.
