We don't know exactly what x is, so the best we can do is simplify these expressions. For 6/x+3, we know that both 6 and 3 are factors of 3, so using the distributive property, 3*2/x+3*1=3*(2/x+1). For 6(x+3), we can use the distributive property to get 6*x+6*3=6x+18. Good luck on the middle expression (I'd recommend using a similar strategy to the one I used), and feel free to ask any questions!

2r2 + 3s3 − r2 + 4t2 − r2 if r = −2, s = −3, and t = 5.

Elza [17]

First, simplify the expression $2r^2 + 3s^3 - r^2 + 4t^2 - r^2.$ Here you have three terms with $r^2,$ group them in the following way:

$2r^2 + 3s^3 - r^2 + 4t^2 - r^2=2r^2-r^2-r^2+3s^3+4t^2=(2r^2-r^2-r^2)+3s^3+4t^2=$

$=r^2(2-1-1)+3s^3+4t^2=3s^3+4t^2.$

Then substitute s=-3 and t=5:

$3s^3+4t^2=3\cdot (-3)^3+4\cdot 5^2=3\cdot (-27)+4\cdot 25=-81+100=19.$

Answer: 19.

A rhombus and a triangle are equal in areas. if the base and height of the triangle are 24.8 cm and 5.5 cm respectively and the

ipn [44]

<h2>Given :-</h2>

Area of Rhombus = Area of Triangle

Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .

Length of one diagonal of the rhombus is 22 cm .

<h2>To Find :-</h2>

Length of other Diagonal

<h2>Solution :-</h2>

As we know that

Area of triangle = ½ × Base × Height

Area = ½ × 24.8 × 5.5
Area = 1 × 12.4 × 5.5
Area = 12.4 × 5.5
Area = 68.2 cm²

<h3 /><h3>Now,</h3><h3 />

Area of rhombus = ½ × D1 × D2

68.2 = ½ × 22 × D2
68.2 × 2 = 22 × D2
136.4 = 22 × D2
136.4/22 = D2
6.2 = D2
D2=6.2

<h2>Hence :-</h2>

<h3>Other Diagonal is 6.2 cm.</h3>
