Answer:

The quotient = 4x - 17 and the remainder = 54

Step-by-step explanation:

$\frac{4x^{2}-5x+3 }{x+3}=4x+\frac{-17x+3}{x+3}$

$\frac{-17x+3}{x+3}=-17+\frac{54}{x+3}$

The quotient = 4x - 17 and the remainder = 54

When plotted on a grid, the paths between four neighborhood houses form the shape of a kite as shown.

KatRina [158]

Answer:

The area of the figure is 1,000 square feet

Step-by-step explanation:

we know that

The area of the kite ABCD

is equal to

$A=\frac{1}{2}[AC*BD]$

where

AC and BD are the diagonals of the kite

we have

$BD=50\ ft\\AC=40\ ft$

substitute

$A=\frac{1}{2}[40*50]=1,000\ ft^2$

A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building. How far up the building do

3241004551 [841]

Sin 45 = X / 14
X = 14 * sin45
X = 7√2≈9.89949
Thus ladder will reach to ≈ 9.9 (rouded-up) foot height in the building
