Answer:

A = 48, and B = 52

Step-by-step explanation:

Simplify 8 = 2 hours to 4 = 1 hour, then multiply 4 times 12 to get the answer to a. The answer to b would be multiplying 4 times 13.

Sloan [31]
So... our numbers... let's say the first one is hmmm "a"
so the second and subsequent are
a
a+1
a+2
a+3
a+4

there, 5 consecutive whole numbers or integers for that matter

now, we know the sum of the square of the first three,
is the same as the sum of the square of the last two

so \bf \begin{cases}
a\\
a+1\\
a+2\\
\textendash\textendash\textendash\textendash\\
a+3\\
a+4
\end{cases}\qquad (a)^2+(a+1)^2+(a+2)^2=(a+3)^2+(a+4)^2

do a binomial theorem expansion on those, solve for "a"

Solve for w.<br> 8(w+2) = 40
AleksAgata [21]

Answer:

  w = 3

Step-by-step explanation:

 8 • (w + 2) -  40  = 0

Pulling out like terms :

3.1     Pull out like factors :

  8w - 24  =   8 • (w - 3)

Equation at the end of step  3  :

 8 • (w - 3)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    w-3 = 0

Add  3  to both sides of the equation :

                     w = 3

One solution was found :

                  w = 3
