Find the area of the rhombus.<br> A=<br> 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

14x - 7y = 21 is a linear equation written in Standard Form. What is the slope and y-intercept ?
Aleonysh [2.5K]
Answer: m=2, b=-3
Explanation: rewrite in slope intercept form - y=2x-3. Subtracting is the same as adding therefore it becomes, y=2x+(-3) then using the formula- y=Mx+b identify the slope which is 2 then identify the y-intercept which would be -3.

Hope that helps! Have a good day :)
