To determine the hypotenuse, use the formula a^2 + b^2 = c^2.

Place 80 as "a" and 39 as "b". Your formula should look like 80^2 + 39^2 = c^2.

Next, plug this into your calculator to get 7921. Then square root 7921.

-3x(x+8)+x+2(9-x-x^2) please show solving steps

Flauer [41]

Answer:

-5x^2 - 25x + 18

Step-by-step explanation:

-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 ) ( original equation )

-3x^2 - 24x + x + 18 - 2x - 2x^2 ( distribute )

-3x^2 - 2x^2 - 24x + x - 2x + 18 ( order them based on the variables . )

( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 ) ( just separated them not a part of solving !! )

-5x^2 - 25x + 18 ( solved , and the answer :) )

Hope its helps !!!

The population of Henderson City was 3,381,000 in 1994, and is growing at an annual rate 1.8%

liq [111]

<h2>In the year 2000, population will be 3,762,979 approximately. Population will double by the year 2033.</h2>

Step-by-step explanation:

Given that the population grows every year at the same rate( 1.8% ), we can model the population similar to a compound Interest problem.

From 1994, every subsequent year the new population is obtained by multiplying the previous years' population by $\frac{100+1.8}{100}$ = $\frac{101.8}{100}$ .
