26.) 3(2)² - 8(-3)²
= 3*4 - 8 + 9
= 12 - 8 + 9 = 13
27.) I 7 - 4(2) I
7 - 8 = -1, but since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.
28.) (-2)² + 2(-3 * 1)
= 4 + 2(-3)
= 4 + (-6) = 4 - 6 = -2
29.) 7(-4)² + 5 / 4(1) - (-5)
=7 * 16 + 5 / 4 + 5
= 112 + 5 / 9 = 117/9 = 13
30.) Product: the result of a multiplication problem
Increased by: multiplied by
3(n * 7)
31.) 2n - 1
<u><em>Answer:</em></u>
a = 3 ft
<u><em>Explanation:</em></u>
The relation between the legs and the hypotenuse of a right-angled triangle can be expressed using the Pythagorean theorem as follows:

<u>In the given triangle, we have:</u>
leg1 = 8 ft and hypotenuse =
ft
<u>Substitute with the givens in the above equation to get the length of the second leg as follows:</u>
(
)² = (8)² + (second leg)²
73 = 64 + (second leg)²
(second leg)² = 9
either second leg = 
or second leg =
as length cannot be negative
Hope this helps :)
Answer:
7
Step-by-step explanation:
h(6)=2(6)–5
h(6)=12–5
=7
X= 1.9
Steps:
16.5-9.2=7.3
9.2-7.3=1.9
Answer:
Number of leashes Bob can make in 2 hours = 7
Number of leashes Bob can make in 1 hour = 7÷2 = 3.5
Let, Bob takes total x hours.
Number of leashes Nina can make in 1 hour = 4
Let, Nina takes total x hours.
∴ The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-
3.5x+4x = 60.
7.5x = 60
This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.
