Answer:

x = 2

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

(4+(4•(x-2)))-(2•(x+1)-x) = 0

Step 2 :

Equation at the end of step 2 :

(4 + 4 • (x - 2)) - (x + 2) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

3x - 6 = 3 • (x - 2)

Equation at the end of step 4 :

3 • (x - 2) = 0

Step 5 :

Equations which are never true :

5.1 Solve : 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2 Solve : x-2 = 0

Add 2 to both sides of the equation :

x = 2

One solution was found :

x = 2

Simplify √49 + [√81 - x(9x = 14)]

eimsori [14]

$\longrightarrow{\green{- 9 {x}^{2} + 14x + 16}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

$\sqrt{49} + [ \sqrt{81} - x \: (9x - 14) ] \\ \\ = \sqrt{7 \times 7} + [ \sqrt{9 \times 9} - 9 {x}^{2} + 14x] \\ \\ = \sqrt{( {7})^{2} } + [ \sqrt{ ({9})^{2} } - 9 {x}^{2} + 14x ] \\ \\ (∵ \sqrt{ ({x})^{2} } = x ) \\ \\ = 7 + (9 - 9 {x}^{2} + 14x) \\ \\ = 7 + 9 - 9 {x}^{2} + 14x \\ \\ = - 9 {x}^{2} + 14x + 16$

A population of flies grows according to the function p(x) = 2(4)x, where x is measured in weeks. A local spider has set up shop

aleksandr82 [10.1K]

The functions are:

$p(x)=2\cdot4^x$ and $s(x)=2x+5$ .

After 2 weeks, under no risk of spiders, the population of the flies is calculated by the function as $p(2)=2\cdot4^2=2\cdot16=32$ .

Similarly, we calculate s(2)=2(2)+5=4+5=9, which means that the spider consumes 9 flies in 2 weeks.

Thus, out of 32 flies, 9 are eaten by the spider, so there are 32-9=23 flies left.

Answer: 23
