The distributive property is just using a certain type of grouping symbols inorder to distribute a particular operation to everything within that grouping symbol.
in the problem 2(a-2), you distribute the 2 to everything within the grouping symbols, giving you 2a-4 as your final evaluated answer. if they wanted you to solve, you set it to zero as such
2a-4=0
2a=4
a=2
Answer:
20 guitars
Step-by-step explanation:
since 12 guitars is equivalent to 60% of the sales then you would divide the 12 guitars by .6 to get the total number of guitars sold
12/.6 = 20 guitars
The simplified expression of (-5m⁷n⁰p⁵)(2m⁴n³p²)³ / -4m⁹n³p²y is 10m¹⁰n⁶p⁹ / y
<h3>How to simplify an expression?</h3>
The expression can be simplified as follows:
using indices law,
aˣ × aⁿ = aˣ⁺ⁿ
aˣ ÷ aⁿ = aˣ⁻ⁿ
Therefore,
(-5m⁷n⁰p⁵)(2m⁴n³p²)³ / -4m⁹n³p²y
Hence,
note
n⁰ = 1
(-5m⁷n⁰p⁵)(8m¹²n⁹p⁶) / -4m⁹n³p²y
Therefore,
-40m⁷⁺¹²n⁹p⁵⁺⁶ / -4m⁹n³p²y
Hence,
-40m¹⁹n⁹p¹¹ / -4m⁹n³p²y
10m¹⁹⁻⁹n⁹⁻³p¹¹⁻²y⁻¹
Hence,
10m¹⁰n⁶p⁹ / y

Answer:
Step-by-step explanation:
Answer:
a. Angle Y is a right angle.
b. The measure of angle Z is 45°.
e. The perpendicular bisector of creates two smaller isosceles triangles.
Step-by-step explanation:
Let x represent the measures of base angles X and Z. Then 2x is the measure of vertex angle Y, and the sum of angles is ...
x + x + 2x = 180°
x = 45°
2x = m∠Y = 90°
so the triangle is an isosceles right triangle which has base angles of 45°.
The perpendicular bisector of XZ is the altitude of the triangle XYZ. It creates two smaller right triangles with acute angles of 45°. Hence, those, too, are isosceles right triangles.
