What is the area of the model in the problem?

nata0808 [166]

Answer:

$A=x^2+12x+27\ units^2$

Step-by-step explanation:

we know that

The area of the model is equal to the area of a rectangle

The area of a rectangle is equal to

$A=LW$

we have

$L=x+9\ units$

$W=x+3\ units$

substitute

$A=(x+9)(x+3)$

Apply distributive property

$A=x^2+3x+9x+27$

Combine like terms

$A=x^2+12x+27\ units^2$

Micheal has a SQUARE garden with a perimeter of 132 feet.Is the area of the garden greater than 1,000 square feet?

Vedmedyk [2.9K]

Well, we know it is a square, so each side is the same length.
SO we can divide the perimeter by 4.
132/4 = 33
SO we know The length is 33 and the width is 33
to find area, we must multiply length times width
33 * 33= 1089
So the area is 1089 ft^2
1089 is greater than 1000
Hope I helped!

kotegsom [21]

Answer:

0.345

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 5, r = 2, p = 0.41, and q = 0.59.

P = ₅C₂ (0.41)² (0.59)⁵⁻²

P = 0.345
