Answer:
Think of the altitude as a line that divides the equilateral triangle into two equal parts.
Each part is a 30, 60, 90 triangle. The altitude of the triangle corresponds to the x side of the equilateral triangle.
So: 9=x , and x=9/.
However, one side of the triangle is actually 2x, so the correct answer is
18/

Answer:</h3><h2>
x + y = -4.125</h2><h3>
Step-by-step explanation:</h3>
When you have a problem with wanting the answer to be negative, you must Add the 2 negative numbers.
-11/8 = - 1 3/8, 11/4 - 2 3/4.
You should take off the negatives for this problem, and just add fractions as usual.
We need common denominators, which is 8.
Our problem is:
1 3/8 + 2 6/8.
We add, 3 + 6 = 9 / 8.
1 1/8.
2 + 1 = 3 + 1 1/8 = 4.125.
Then, we put the negative sign.
Therefore x + y is correct since the value is negative, -4.125.
Best of Luck to you.

Answer:
You cannot
Step-by-step explanation:
You cannot multiply a 2×3 matrix by a 2×2 matrix. The number of columns in the first matrix ( 3 ) is not the same as the number of rows in the second matrix ( 2 ).
