Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
Yes, I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.
<h3>What is a right-angled triangle?</h3>
A right-angled triangle serves as the triangle having one of its angles equal to 90 degrees.
It should be noted that the other two angles sum up to 90 degrees., hence I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.

The answer for this is 42. just subtract 152 from 68 and then divide that by 2.
Answer:
the numbers 20, 60, 80, and 120 go on the x axis
the numbers, 3, 9, 12, and 18 go on the y axis
so you go to 20 on the bottom and go up to number 3
60 go up to number 9
80 go up to number 12
120 go up to number 18
Step-by-step explanation:
19.47 is the answer. 29.5 * .66 or 66% is 19.47
