Corrected Question:
The length of a rectangle is (t – 8) units, and its width is (t + 11) units. Which expression can represent the area of the rectangle?
Answer:
t² + 3t - 88
Step-by-step explanation:
Given:
Rectangle of;
length = (t - 8) units
width = (t + 11) units
The area A of a rectangle is given by;
A = length x width ----------------------------------(i)
Substitute the given length and width into equation (i) as follows;
A = (t - 8) x (t + 11) [expand the brackets]
A = t² -8t + 11t - 88
A = t² + 3t - 88
Therefore, the area is
(t² + 3t - 88) square units
2 1/2= 5/2
3 1/4= 13/4
5/2•13/4= 65/8 or 8/18
Hope this helped!

In this question, Suzan is taking 5 marble from a bag containing four red marbles, four green ones, two white ones, and two purple ones. The total marble in the bag should be: 4+4+2+2= 12. The question is how much the probability to get <span>two red, 1 green, 1 white and 1 purple. Then the probability would be:
4*3*4*2*2/ 12*11*10*9*8= 192/ 950400= 1/495</span>
