Answer:you can multiple a letter only by its self not other letters so you can do x times x which is 2x but you can’t do x times y.
Step-by-step explanation:
In a right triangle, this formula can be used:
a^2 + b^2 = c^2
when a and b are the legs and c is the hypotenuse.
Substitute the numbers from the problem into the formula.
14^2 + b^2 = 18^2
Simplify.
196 + b^2 = 324
b^2 = 128
b = square root of 128 = 11.3137...
When 11.313 is rounded to the nearest tenth, it is 11.3
The length of the other leg is 11.3 centimeters.
Hope this helps!
Answer:
The answer is x=12
Step-by-step explanation:
3x - 6 = 30
3x-6+6=30+6
3x=36
To find x divide both sides by 3.
3x/3=36/3
x=12
Answer:
5
Step-by-step explanation:
perpendicular slopes multiply to -1
lets say m is the missing slope
-1/5*m=-1 so m=5
It Is the number x2, then +1. so 30x2+1
