The perimeter of a rectangle is 84cm.
Its shortest side has a length of 3cm.
State the length of the longest side.

Answers

Answer 1

Answer:

39 cm

Step-by-step explanation:

The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.

Let us use w as 3 cm.

The perimeter of the rectangle is 2(3) + 2l = 6 + 2l

6 + 2l = 84 cm

We move the 6 to the left hand side and it goes from positive to negative.

2l = 84 - 6cm

2l = 78 cm

Divide both sides by 2.

l = 39 cm

There you have the answer for side l.

Hope this helps.

Step-by-step explanation:

g([tex](\sqrt{x+1}^2+3)/(\sqrt{x+1} )[/tex]

rewrite [tex]\sqrt{x+1}^2[/tex] as x +1

g [tex](\sqrt{x+1}^2)[/tex] = [tex]\frac{x+1+3}{\sqrt{x+1} }[/tex]

add 1+3

g[tex](\sqrt{x+1}^2)[/tex]=[tex]\frac{x+4}{\sqrt{x+1} }[/tex]

combine and symplify

[tex]g{\sqrt{x+1} } *\frac{{x+4 (\sqrt{x+1}) } }{{x+1} }[/tex]

reorder factors of the second side

[tex]g{\sqrt{x+1} } *\frac{{\sqrt{x+1} (x+4) } }{{x+1} }[/tex]

take out the root x+1

and you are left with A

f(g(x))

substitue g into f

f([tex]f{\sqrt{x+3} } =\((\sqrt{x+3})^2 +9}[/tex]

rewrite sqrroot x+3 as x+3

[tex]f{\sqrt{x+3} } =\(x+3 +9}[/tex]

Now add 3+9

[tex]f{\sqrt{x+3} } =\(x+12}[/tex]

we get x+12

Now for domain

[tex]f{\sqrt{x+3} } =\((\sqrt{x+3})^2 +9}[/tex]

set the radicand root sqr x+3 >= 0 to find the expression defined

[tex]x+3\geq 0[/tex]

subtract 3 from both sides

The Above statement is incorrect, because if the positive number is equal to the numerical value of negative number then their sum will be zero, and If the numerical value of positive number is greater than that of negative number then the sum will be a positive number, so the probability is of both three, the sum can be positive, negative as well as zero.

The above statement is false.

Answer:

  D: 21

Step-by-step explanation:

The first term is (a1). The third term is (a1)r². The product of these terms is ...

  (a1)(a1)r² = ((a1)r)², the square of the second term.

The missing term is √(7·63) = √441 = 21.

_____

Additional comment

In consideration of the above, you can also see that the common ratio can be found from ...

  a3/a1 = ((a1)r²)/(a1) = r² = 63/7 = 9

Then the common ratio is r = √9 = 3, and the second term is 7·3 = 21.
