To find the area of a parallelogram, we need to multiply the base times the altitude.

We have that the base is equal to 8cm, and the altitude is equal to 2.2cm (the altitude is perpendicular to the base). Then, we have:

A_{\text{parallelogram}}=b\cdot h=8\operatorname{cm}\cdot2.2\operatorname{cm}=17.6\operatorname{cm}^2

Therefore, the area of this parallelogram is equal to 17.6 sq. centimeters.

denis23 [38]

Answer:

4.8 inches

Step-by-step explanation:

Given: The largest frog in the world is goliath which is 12 inches long.

           The smallest frog is about 2.5 as long as the goliath.

Lets assume the length of smallest frog be "x".

As given, smallest frog is about 2.5 as long as the goliath.

∴ we can form equation as 2.5x= 12\ inches

Solving the equation to find the value of x

2.5x= 12

Dividing both side by 2.5

⇒ x= \frac{12}{2.5}

∴ x= 4.8\ inches

Hence, the length of smallest frog is 4.8 inches.

Alex

Answer:

R = 6S/T

Step-by-step explanation:

R ∝ S/ T

》R = kS/ T

》k = RT/ S

If R = 8 when S = 4 and T = 3

then, k = (8 × 3)/ 4

k = 6

∴ R = (6 × S)/ T

Plz help if u can 20 pt please just don't take the points..
sergey [27]

Answer:

b. 28x + 8y +2

Step-by-step explanation:

you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.

-2*3x= -6x

-2*12y= -24y

-2*-5= 10 (remember neg times neg = pos)

-2*17= 34x

-2*-16y=32y

-2*4= -8

Now combine like terms

34x-6x= 28x

32y-24y=8y

10-8=2

Write the expression:  28x + 8y +2
