Answer:

875

Step-by-step explanation:

Rectangle ABCD is SIMILAR to rectangle EFGH this means that they are proportionately the same as each other. Therefore any changes we know about one side apply to the whole shape. Since we know side EF is 5 times side AB we also know side EH is 5 times side AD. If 5 times AD is 35, AD must be 7. Multiply that by five, and you have the value of EH, which is 35. multiply that by EF (25), and you have your answer. Hope this helps!

Answer:

<em>As </em><em>we </em><em>can </em><em>see </em><em>that </em><em>both </em><em>rectangles </em><em>are </em><em>similar</em><em>. </em>

Step-by-step explanation:

AB= 5ft and EF = 25

Area of rectangle ABCD

5 * BC = 35

Therefore BC= 7

Now

The value of FG is 35 ft

hence now we can calculate the area of rectangle EFGH

= 25 *35

= 875 square foot

40x=10x^2+41 <br><br> Identify the number of solutions and their types using the discriminant

nydimaria [60]

Number of solutions: no roots

Type of solution: Not Real

Step-by-step explanation:

We need to identify the number of solutions and their types using the discriminant.

We are given: $40x=10x^2+41\\$

Rearranging:

$40x-10x^2-41=0\\10x^2-40x+41=0$

Discriminant can be found by: $b^2-4ac$

where b=-40, a=10 and c=41

Putting values:

$b^2-4ac\\=(-40)^2-4(10)(41)\\=1600-1640\\=-40\\$

So, Discriminant is -40

If the discriminant is less than zero i.e -40 then there are no real roots.

So, Number of solutions: no roots

Type of solution: Not Real

Keywords: discriminant
