Answer:

Step-by-step explanation:

Remark

There are two similar triangles in the diagram: ΔYZX and ΔVWX.

That being true a ratio can be set up as

VW / ZY = WX / XZ

Givens

VW = 104

ZY = 8

WX = ?

XZ = 6

Solution

104 / 8 = WX / 6

104 * 6 / 8 = WX

WX = 78

So the width of the lake is 78 meters

Rewrite in simplest terms: (9x+5)-(-2x+10)(9x+5)−(−2x+10)

$\implies {\blue {\boxed {\boxed {\purple {\sf { 18 {x}^{2} - 69x - 55}}}}}}$

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

$= (9x + 5) - ( - 2 x+ 10)(9x + 5) - ( - 2x + 10)$

$= (9x + 5) + 2x (9x + 5) - 10(9x + 5) - ( - 2x + 10)$

$= 9x + 5 + 18 {x}^{2} + 10 x- 90x - 50 + 2x - 10$

Collect the like terms.

$= 18 {x}^{2} + (9x + 10x- 90x + 2x) + (5 - 50 - 10)$

$= 18 {x}^{2} + (21x - 90x) +(5 - 60)$

$= 18 {x}^{2} - 69x - 55$

Use the functions and the scenario to solve the problem.

Naily [24]

Answer:

Leanne is correct. It is important that g(x) is subtracted from f(x).

Shiloh is incorrect. She subtracted f(x) from g(x), and subtraction isn't commutative.

*Just took the test, got the answer correct!! Hope this helps!
