Two different sized triangles have a scale factor of 2:3. If the hypotenuse ( the longest side ) of the bigger triangle measures

OlgaM077 [116]

Answer:

16 in

Step-by-step explanation:

The 3 part of the ratio represents 24 inches.

Dividing by 3 gives the value of one part of the ratio.

24 in ÷ 3 = 8 in ← value of 1 part of the ratio, thus

2 parts = 2 × 8 in = 16 in ← hypotenuse of smaller triangle

Find the difference quotient f(x)=2x^2+5x

expeople1 [14]

Step-by-step explanation:

Step 1: Find the difference quotient

$f(x+h) = 2(x+h)^2 + 5(x+h)$

$f(x+h) = 2(x^2+2xh+h^2)+5x+5h$

$f(x+h) = 2x^2+4xh+2h^2+5x + 5h$

$f(x) = 2x^2 + 5x$

Plug it into the formula

Difference Quotient: $\frac{f(x+h)-f(x)}{h}$

$\frac{2x^2+4xh+2h^2+5x+5h - (2x^2+5x)}{h}$

$\frac{2x^2 - 2x^2 + 4xh + 2h^2 + 5x - 5x + 5h}{h}$

$\frac{2h^2+4xh+5h}{h}$

Pull out an h

$\frac{h(2h+4x+5)}{h}$

$2h+4x+5$

Answer: $2h+4x+5$

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 9 rows of the same length, he has 3 chairs left ov

exis [7]

9x + 3 = 7x +19

2x + 3 = 19

2x = 16

x = 8

So, x (8) is the number of chairs in each row with these setups.

Plug 8 into one of the equations and you will find how many chairs total there are.

9(8) + 3 = 75

There are 75 chairs total
