In Rhombus ABCD if BD is 24 ft and AD is 15 ft, then what is the length of AC?

Evgen [1.6K]

Answer:

AC = 24ft

Step by Step Explanation.

Given.

Rhombus.

BD = 24ft

AD = 15ft

Required

Length of AC

A rhombus has 4 equal sides; hence, the given shape will be regarded as a parallelogram and not rhombus (see attachment for diagram)

The opposite sides of a parallelogram are always of equal length

From the attached diagram (not drawn to scale), side AC opposites side BD

Given that BD = 24ft, then

AC = BD = 24ft.

Hence, AC = 24ft

Factor completely and then place the factors in the proper location on the grid. 8 y^2 + 6 y + 1

Firlakuza [10]

Answer:

(4y + 1)(2y + 1) -- Unfortunately I can't help with the grid part

Step-by-step explanation:

Multiply the a and c term (8 * 1) to get 8. Think of what factors of 8 would add up to your b term (6), which would be 4 and 2. Rewrite your equation as 8y^2 + 4y + 2y + 1 and consider one half at a time and factor them individually. For the left, that'd be 4y(2y + 1), and for the right, you can't factor anything so it's just 1(2y + 1). Check that the things inside the parentheses are the same, which they are, and add the things you factored out and multiply that by the part in the parentheses for (4y + 1)(2y + 1).

Artemon [7]

Answer:

We have been given that D'Quan grandmother made a quilt for his bed. The quilt is 2.44 meters long and 1.83 meters wide.

We can see that quilt is in form of a rectangle and area of a rectangle equals to width times length.

$\text{Area of rectangle}=\text{length}*\text{Width}$
