Simplify both sides −8x − 5x = −13x which would equal −13x = −13x

Than add 13x to both sides: −13x + 13x = −13x + 13x

So, the answer is 0=0,
which could be said as all real numbers are solutions.

Answer:

Step-by-step explanation:

$(\frac{3}{4})^6 \times (\frac{16}{9})^5=(\frac{4}{3})^{x+2}$

$\frac{3^6}{4^6} \cdot \frac{16^5}{9^5}=\frac{4^{x+2}}{3^{x+2}}$

$\frac{3^6}{4^6} \cdot \frac{(4^2)^5}{(3^2)^5}=\frac{4^{x+2}}{3^{x+2}}$

$\frac{3^6}{4^6} \cdot \frac{4^{10}}{3^{10}}=\frac{4^{x+2}}{3^{x+2}}$

$\frac{3^6}{3^{10}} \cdot \frac{4^{10}}{4^6}=\frac{4^{x+2}}{3^{x+2}}$

$3^{-4} \cdot 4^{4}=4^{x+2}3^{-(x+2)}$

This implies

x+2=4

and

-(x+2)=-4.

x+2=4 implies x=2 since subtract 2 on both sides gives us x=2.

Solving -(x+2)=-4 should give us the same value.

Multiply both sides by -1:

x+2=4

It is the same equation as the other.

You will get x=2 either way.

Let's check:

$(\frac{3}{4})^6 \times (\frac{16}{9})^5=(\frac{4}{3})^{2+2}$

$(\frac{3}{4})^6 \times (\frac{16}{9})^5=(\frac{4}{3})^{4}$

Put both sides into your calculator and see if you get the same thing on both sides:

Left hand side gives 256/81.

Right hand side gives 256/81.

Both side are indeed the same for x=2.

What would the total area be??

timurjin [86]

Answer:

1,560,000 mm²

Step-by-step explanation:

A= $\frac{(1600*600)}{2}$ This would make shape A's area 480,000.

B= $\frac{(600*600)}{2}$ This would make shape B's area 180,000.

C= $\frac{(1000*600)}{2}$ This would make shape C's area 300,000.

D= 1000×600 This wouls make D's area 600,000.

Now you add up all of the areas;

480,000+180,000+300,000+600,000= 1,560,000 mm²
