Answer:
1
Step-by-step explanation:
Hopefully this is correct. say your starting point is {B} and want to go to {A}. clockwise is always to the left and the mark {B} is on a 90 degree angle both ways. so you would need to go 90 degrees clockwise to get around to A.
I am just a middle schooler hopefully this piece of information may help you figure it out.
Answer:
x = 30
Step-by-step explanation:
here 50 is hypotenuse as it is opposite of 90 degree.
x and x + 10 are the two other smaller sides of a right angled triangle respectively.
using pythagoras theorem,
a^2 + b^2 = c^2
x^2 + (x + 10)^2 = 50^2
x^2 + x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 - 2500 = 0
2x^2 + 20x - 2400 = 0
2(x^2 + 10x - 1200) = 0
x^2 + 10x - 1200 = 0
x^2 + (40 - 30) - 1200 = 0
x^2 + 40x - 30x - 1200 = 0
x(x + 40) - 30(x + 40x) = 0
(x + 40)(x - 30) = 0
either x + 40 = 0 OR x - 30 = 0
x = 0 - 40
x = -40
x - 30 = 0
x = 30
x = -40,30
since the length and distance is not measured in negative ur answer will be 30

thank u very much . At first i was wrong and giannathecookie i m really sorry
Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem
