8 0

The answer is 76.

2 times 5 is 10. There are two sides so 10 times 2 is 20.

4 times 5 is 20. There are two sides so 20 times 2 is 40.

4 times 2 is 8. There are two sides so 8 times 2 is 16.

20+40+16 is 76.

The product of two rational numbers is (-28/81). If one of them is (-2/3), the find the other.

KatRina [158]

Answer:

The other rational number is $\dfrac{14}{27}$ .

Step-by-step explanation:

First rational number is $\dfrac{-2}{3}$

Let other rational number is $\dfrac{x}{y}$

The product of two rational numbers is $\dfrac{-28}{81}$

According to question,

$\dfrac{x}{y}\times \dfrac{-2}{3}=\dfrac{-28}{81}$

Multiplying both sides by (-3/2) such that,

$\dfrac{x}{y}\times \dfrac{-2}{3}\times \dfrac{-3}{2}=\dfrac{-28}{81}\times \dfrac{-3}{2}\\\\\dfrac{x}{y}=\dfrac{14}{27}$

So, the other rational number is $\dfrac{14}{27}$ .

The length of a rectangle is 5 in longer than its width. if the perimeter of the rectangle is 34 in , find its area.

shtirl [24]

Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w

1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in

l= w+5
l= 6+5
l=11 in

A= lw= (11)(6)= 66in²

Answer:
Area of rectangle is 66 in².
