What is the value of s and the length of side BC if ABCD is a rhombus?

Natali5045456 [20]

Step 1

<u>Find the value of s</u>

we know that

In a Rhombus all sides are congruent

so

$AB=BC=CD=DA$

$AB=9s+29\\CD=10s-16$

equate AB and CD

$9s+29=10s-16\\$

Combine like term

$10s-9s=29+16\\$

$s=45\ units$

<u>The answer Part a) is</u>

the value of s is $45\ units$

Step 2

<u>Find the value of side AB</u>

$AB=9s+29$

substitute the value of s

$AB=9*45+29=434\ units$

Remember that the sides are congruent

$AB=BC=CD=DA$

therefore

<u>the answer Part b) is</u>

The length of the side BC is $434\ units$

zalisa [80]

Answer:

300. In this case, it's very easy to do this percentage inflation. Since 20 is a multiple of 100, and we want to know the 100%, you just multiply the 20 by 5 to make it 100. Along with this, you multiply the 60 by 5 as well, which gives you 300.

Which equations are equivalent to the expression below ? Check all that apply

taurus [48]

It looks like selections A and C are identical. (Neither is equivalent to 9^x.)

If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.

Of course, D evaluates to 9^x, so is equivalent.

Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).

The applicable choices appear to be

... B. 3^(2x)

... D. (3*3)^x

... F. (3^x)*(3^x)
