Answer:
1. 2A + 3A
2. 2A - B
3. 2A
4. 2(A-B)
Step-by-step explanation:
When multiplying matrix by a number you just multiply each number in the matrix by whatever you are multiplying. When adding 2 matrices you just add the corresponding number in each matrix. Ex: You add the top left number to the top left number. The same goes with subtraction.
Answer:
Number of teaspoon of red paint = 16
Step-by-step explanation:
Given:
Mixture contain = 4 teaspoon red paint and 10 teaspoons blue paint
New Mixture = 40 teaspoons blue paint
Find:
Number of teaspoon of red paint
Computation:
4 teaspoon red paint / 10 teaspoons blue paint = Number of teaspoon of red paint / 40 teaspoons blue paint
Number of teaspoon of red paint = 16
The answer is 83x hope this helps
The combinations of ordered triplets that are possible is equal to: A. 18.
<h3>How to find the possible number of ordered triplet?</h3>
Since the common difference (d) between the consecutive terms in an arithmetic progression (AP) is constant, we have:
d = y - x = z - y
Rearranging the terms, we have:
x = y - d
z = y + d
From the given equation:
x + y + z = 30
y - d + y + y + d = 30
3y = 30
y = 30/3
y = 10.
So the arithmetic progression (AP) is given by:
(10 - d), 10, (10 + d)....
Since the common difference (d) is a natural number which would be from 1 to 9, the combinations of ordered triplets that are possible is as follows:
Number of possibilities = 9 × 2
Number of possibilities = 18.

1. 169, because the angles of a hexagon add up to 720. the angles given add up to 551. 720 - 551 = 169.
2. 27.225, as the formula for the area of a triangle = 1/2 x base x height
3. 95, area = b x h
4. 56.25
