Answer:
20
Step-by-step explanation:
which side is x ? the Hypotenuse - the side opposite of the 90 degree angle ? or is it one side touching the 90 degree angle ?
that is important. we need to know which side is the Hypotenuse to make the right calculations.
if I assume x is the Hypotenuse, then the calculation follows Pythagoras like this
x² = 12² + 16² = 144 + 256 = 400
x = sqrt(400) = 20
but just in case, if x is a side touching the 90 degrees angle, then the would look like this (depending on which of the other sides is the Hypotenuse)
either
12² = 16² + x²
144 = 256 + x²
-112 = x²
that did not work. a square root of a negative number did not work for actual distances.
or
16² = 12² + x²
256 = 144 + x²
112 = x²
x = sqrt(112) = 10.58
The value of y should be 8
Answer:
this is simple once you get the hang of it!! as you see in the chart they gave you, 1=3.15, meaning you graph it (1, 3.15) and so on. all you do is multiply each number (for example, 4) times 3.15 and (4x3.15=6). so 3.15 times all the x-axis numbers and graph it (x, y).. hope this makes sense :)
Answer:
6x+12
Step-by-step explanation:
This is an equivalent expression as all I did was simplify the expression using the distributive property. (6(x)) + (6(2)) = (6x) + (12) = 6x + 12
shown in reverse to prove this is equivalent would look like this. 6x+12 = (6(x)) + (6(2)) = 6(x+2)
