Answer:

a² + b² = c²

1. 45² + 36² = c²

2025 + 1296 = c²

3321 = c²

√3321 = √c²

57.6 = c

2. a² + 4.5² = 12.5²

a² + 20.25 = 156.25

a² + 20.25 - 20.25 = 156.25 - 20.25

a² = 136

√a² = √136

a = 11.7

Eva8 [605]

Answer:

$-5x-5$

Step-by-step explanation:

original functions:

$f(x)=3x-8\\g(x)=8x-3$

Subtract the polynomials:

$f(x)-g(x) = (3x-8) - (8x-3)$

Distribute the negative sign:

$3x-8-8x+3$

Combine like terms:

$(3x-8x)+(-8+3)$

Add like terms:

$-5x-5$

Hello! First we should note that the shape of the figure can be broken down into two rectangular prisms, so that the expression will look like:

Volume = (w • h • l) vertical rectangular prism + (w •h • l) horizontal rectangular prism

Thus Volume = (7 • 3 • 3) + (9 • 3 • 4)
