Answer:
A and B are correct
Step-by-step explanation:
Answer:
80.94 cm squared
Step-by-step explanation:
The area of a parallelogram is: A = bh, where b is the base and h is the height perpendicular to the base.
Right here, we see that we're given two different possible bases: 8.9 and 11.4. However, when we look at the height, it's perpendicular to the base with length 11.4, so we know to disregard the base with length 8.9 and only focus on the 11.4. Then b = 11.4 and h = 7.1. So, the area is:
A = 11.4 * 7.1 = 80.94
Thus, the answer is 80.94 cm squared.
Hope this helps!
A is irrational but b is rational. This is because for b you can work out both square root of 64 (8) and square root of 4 (2). But for a, the square root of 5 is an irrational number :)
Step-by-step explanation:
Example: (5,2)
On a graph, the 5 goes on the x-axis and the 2 goes on the y-axis.
Also, in the world of variables, and the alphabet, x is before y.
So x represents the first number in an ordered pair.
