PLEASE HELP ASAP! EXPLAIN THE ANSWER!

Stells [14]

Answer:

<h3>1863 m squared</h3>

Step-by-step explanation:

So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)

So:

12 x 23 = the missing square = 276

31 x 69 = rectangle with the square = 2139

Total area = 2139 - 276 = 1863

Solve the following equation for h.<br> r+3Q/h=t

Arada [10]

Answer:

$\bold{h=\dfrac{3Q}{t-r}}$

Step-by-step explanation:

$\bold{r+\frac{3Q}h=t}\\-r\qquad\ -r\\\bold{\frac{3Q}h=t-r}\\\cdot h\qquad \cdot h\\ \bold{3Q=(t-r)h}\\^{\div(t-r)\quad\div(t-r)}\\\bold{\dfrac{3Q}{t-r}=h}$

Or, if you mean (r+3Q)/h=t:

$\bold{\frac{r+3Q}h=t}\\{}\ \ \cdot h\quad\ \cdot h\\\bold{r+3Q=ht}\\{}\ \ \div t\qquad \div t\\\bold{\dfrac{r+3Q}{t}=h}\\\\\bold{h=\dfrac{r+3Q}{t}}$
