Doreen is flipping two fair coins. What is the probability that both coins land on heads?

andrezito [222]

Answer:

There are four different possible outcomes: both coins are heads, the red coin is heads and the blue coin is tails, the red coin is tails and the blue coin is heads, or both coins are tails. Each outcome has equal probability. So the probability of both being heads is 1/4.

A rectangular garden has a length of (2y - 4) feet and a width of 4y^2 feet. How do you find the perimeter of the garden

Ber [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 {y}^{2} + 4y - 8}}}}}$

Step-by-step explanation:

Given,

Length of a rectangular garden ( l ) = 2y - 4

Width of a rectangular garden ( w ) = 4y²

Perimeter of the garden = ?

Finding the perimeter of a rectangular garden having length of 2y-4 and width of 4y²

$\bold{ \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}}$

$\longrightarrow{ \sf2(2y - 4 + 4 {y}^{2}})$

Distribute 2 through the parentheses

$\longrightarrow{ \sf{4y - 8 + 8 {y}^{2} }}$

Arrange it in standard form

$\longrightarrow{ \sf{8 {y}^{2} + 4y - 8}}$

Hope I helped!
