Find the value of y for a given value of x, if y varies directly with x. if y = -252 when x = 84, what is y when x = 74? explain with steps, you!

Step-by-step explanation:

if x =1  y = ?

y = -252/84

y = -3

y = -3*74

y = - 222

we need to calculate the value of y when x =1

we have to divide the value of y by value of x by doing this we can get the value of y is -3 when x=1

when x = 74 we have to multiply the value of x & y (74 *-3)

so the answer is -222

OR

84 / -252 = 74 / y

84y = (-252)(74)

84y = -18,648

   y =  -18,648 / 84

   y = - 222

answer y = -222 when x = 74

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
