The answer is 15h² + 26h - 21

<span>(5h – 3)(3h + 7) = 5h * 3h + 5h * 7 - 3 * 3h - 3 * 7 =
= 15h</span>² + 35h - 9h - 21 =
= 15h² + 26h - 21

Martha (from problem 9) has some expenses each week. Each week she buys $9.72 worth of

Verdich [7]

if Martha is not earning money to pay it back, it would be negative. Each week, she loses -9.72 dollars. so -9.72 x 3 weeks = your problem. I'll let you take it from there and solve the rest

What is the solution to the equation below? Round your answer to two decimal places. 8*9^x=35.68

Alecsey [184]

Answer:

$x=0.68$

Step-by-step explanation:

we have

$8(9^x)=35.68$

solve for x

Divide both sides by 8

$8(9^x)/8=35.68/8$

$(9^x)=4.46$

Apply log both sides

$log(9^x)=log(4.46)$

Applying logarithmic property

$\log a^x=x\log a$

$(x)log(9)=log(4.46)$

$x=log(4.46)/log(9)$

$x=0.68$

Answer:

42 meters

Step-by-step explanation:

Given

See attachment for complete question

Required

Calculate distance FC

FC is calculated as:

$FC = Path\ 1 + Path\ 2$

Where

$Path\ 1 = FB$

$Path\ 2 = BC$

Considering $\triangle FEB$ , we have:

$FB^2 = FE^2 + BE^2$ --- Pythagoras theorem

Where

$FE = FD - BA$

$FE = 22m - 15m$

$FE = 7m$

and

$BE = CD - CA$

$BE = 32m - 8m$

$BE = 24m$

So:

$FB^2 = FE^2 + BE^2$

$FB^2 = 7^2 +24^2$

$FB^2 = 49 +576$

$FB^2 = 625$

Take square roots of both sides

$FB = 25$

So:

$Path\ 1 = 25$

Considering $\triangle BAC$ , we have:

$BC^2 = BA^2 + AC^2$ --- Pythagoras theorem

Where:

$BA = 15$ and $AC = 8$

So, we have:

$BC^2 = 15^2 + 8^2$

$BC^2 = 225 + 64$

$BC^2 = 289$

Take square roots of both sides

$BC = 17$

So;

$Path\ 2= 17$

Recall that:

$FC = Path\ 1 + Path\ 2$

$FC = 25 + 17$

$FC = 42$
