Mari has 39 square feet of patio bricks. Each square brick has sides 1 foot long. What is the greatest perimeter of a rectangle

Margaret [11]

I think you would do 39 x 4 because if the SQUARE brick has sides 1 foot long, you count up the sides and get 4 feet. She has 29 square feet of patio bricks so you would multiply 39 x 4. I don't know if this is correct. Hopefully I helped!

on a large college campus, 84% of the students report drinking alcohol within the past month, 33% report using some type of toba

Natasha_Volkova [10]

Answer: 0.31

Step-by-step explanation:

Let A denotes the event that the students report drinking alcohol and B denotes the students report using some type of tobacco product .

Given : P(A) =0.84 ; P(B)=0.33 and P(A∪B)=0.86

We know that $P(A\cap B)=P(A)+P(B)-P(A\cup B)$

Then, the probability that the student both drunk alcohol and used tobacco in the past month is given by :-

$P(A\cap B)=0.84+0.33-0.86=0.31$

Hence, the probability that the student both drunk alcohol and used tobacco in the past month = 0.31

Solve x2 + 8x + 8 = 0 by completing the square. Which equation is used in the process?

garri49 [273]

x² + 8x + 8 = 0

x² + 8x + 8 + 8 = 0 + 8

x² + 8x + 16 = 8

x² + 4x + 4x + 16 = 8

x(x) + x(4) + 4(x) + 4(4) = 8

x(x + 4) + 4(x + 4) = 8

(x + 4)(x + 4) = 8

(x + 4)² = 8
