Answer:
30ft²
Explanation:
The area of the plywood that she has:
8 ⋅ 9
=72ft²
The area of the plywood she cut
7 ⋅ 6
=42ft²
The area discarded should be:
72ft² - 42ft²
= 30ft²
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:

For the slope of ln:

For the slope of mn:

- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

Answer:
Tax multiplier = 3
Explanation:
Given:
Current MPC = 0.75
Find:
Tax multiplier
Computation:
Tax multiplier = MPC / [1 - MPC]
Tax multiplier = 0.75 / [1 - 0.75]
Tax multiplier = 0.75 / 0.25
Tax multiplier = 3
