Help asap please i don't know the answer lol

Answer:

H

Step-by-step explanation:

The parallel line BC divides the sides AD and AE in proportion, that is

$\frac{AB}{BD}$ = $\frac{AC}{CE}$ , that is

$\frac{2}{3}$ = $\frac{AC}{4}$ ( cross- multiply )

3AC = 8 ( divide both sides by 3 )

AC = $\frac{8}{3}$ = 2 $\frac{2}{3}$ , hence

AE = AC + CE

= 2 $\frac{2}{3}$ + 4 = 6 $\frac{2}{3}$ → H

Prove that if b is a square matrix then b+b^t is symmetric

WARRIOR [948]

A matrix $\mathbf X$ is symmetric if $\mathbf X=\mathbf X^\top$ . We have

$(\mathbf B+\mathbf B^\top)^\top=\mathbf B^\top+(\mathbf B^\top)^\top=\mathbf B^\top+\mathbf B=\mathbf B+\mathbf B^\top$

and so $\mathbf B+\mathbf B^\top$ is indeed symmetric.

If the length of a rectangular garden is 2 feet less than the length of a house and the width of the garden is 5 feet less than

Goshia [24]

Answer:

A(h) = h²/2 - 6*h + 10

Step-by-step explanation:

The garden is rectangular, and area of a rectangle is:

A(r) = L*w

Where L is the length and w is the width of the rectangle

Now if we call "h" the length of the house, we have the following expressions

L = h - 2 and

w = h/2 - 5

The expression for the area f the ectangle as a function of the length of the house is:

A(h) = ( h - 2 )* ( h/2 -5 )

A(h) = h²/2 - 5*h - h + 10

A(h) = h²/2 - 6*h + 10
