Answer:
10. 2
11. -16
Step-by-step explanation:
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>

Answer:
or 
Step-by-step explanation:
Step 1: Apply the fraction rule: 
Step 2: Cross-cancel common factor: 5
Step 3: Multiply fractions: 
Step 4: Multiply the numbers: 
Step 5: Multiply the numbers: 
Therefore, the answer is or in the simplified form;
Answer:
Sometimes this fraction can be further simplified by dividing the numerator and the denominator by their greatest common factor. ... Divide the numerator by this number. If the result is zero, the simplified slope of the line is also zero.
