Find the area of the rhombus. A= square units

mylen [45]

Answer: A=70 square units

Step-by-step explanation:

The area of a triangle can be found using the formula $A=\frac{1}{2} bh$

Let 5=h and 7=b

Plug in the values and solve

$A=\frac{1}{2} (7)(5)$

$A=17.5$

However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.

$A=17.5*4$

$A=70$

(x+8)(x-5) <img src="https://tex.z-dn.net/?f=%20%28x%20%2B%208%29%28x%20-%205%29%20" id="TexFormula1" title=" (x + 8)(x - 5)

Katen [24]

Answer: $\huge\boxed{\ x^2+3x-40}$

My step-by-step explanation:

1. First thing we do is: Distribute

(x+8)(x−5)x

(x−5)+8(x−5)

2. Second thing:Distribute

x(x−5)+8(x−5)

x^2−5x+8(x−5)

3.Third thing: Distribute

x^2−5x+8(x−5)

x^2−5x+8x−40

4. Fourth thing: Combine like terms

x^2−5x+8x−40

x^2+3x−40

5.And finnaly we find: The solution

x^2+3x−40

Good Luck!
