Answer:

Step-by-step explanation:

a. The area of a rectangle is width * length. The width is 5x, and the length is 7x-2. This means the area is 5x*(7x-2). Distributing the 5x, we find that the area of the rectangle is 35x^2-10x.

b. To find the area when x is 4, we plug x=4, so 35*4^2-10*4=560-40=520.

c. same as above, we plug x=7, and get 1645 as our area.

A single, six-sided die is rolled. Find the probability of rolling an even number or a number less than 6 .

boyakko [2]

Answer:

P=1

Step-by-step explanation:

P(even or less than 6) = P(even)+P(less than 6) -P(even ∩ less than 6)

P(even)=3/6 (numbers 2,4, and 6)

P(less than 6) =5/6 (numbers 1,2,3,4, and 5)

P(even ∩ less than 6)=2/6 (numbers 2 and 4)

(3/6)+(5/6) -(2/6) = (3+5-2)/6 = 6/6=1
