3(y+5)+9=30 40/n-2=4
(k+6)squared =64
(c-3)squared=16
answer the missing variables to complete the equation

Direct variation problems are solved using the equation y = kx. ... Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2. ... Example 3 – If c varies directly as the square root of d, and c = 6 when d = 256, find c ...

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
