Aflower garden has 6 flowers each flower has 7 petals how many petals are on the 6 pink flowers?

There are 42 petals on the 6 flowers.

Step-by-step explanation:

Given:

A flower garden has 6 flowers.

Each flower has 7 petals.

Now, to find number of petals on the 6 flowers.

As given:

Number of flowers = 6.

Number of petals each flower has = 7.

Thus, we multiply number of flowers to the number of petals to get the total number of petals:

Number of 6 petals = Number of flowers × Number of petals each flower has.

Therefore, there are 42 petals on the 6 flowers.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
