If the 3’s were exponents then... i got 50r3
how i solved:
39r3 + 11r3 + 45s3 - 5s3 - 40s3
50r3 + 40s3 - 40s3
50r3 + 0
= 50r3
Answer:
tan B = 5/12
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adj side
tan B = 5/12
Well, for number three. You know that the length of the RECTANGULAR garden is 6.8 meters. Since it is a rectangle the garden will have 4 sides:two lengths and 2 widths. an easy way to find the width is to multiply the single length by 2, so 6.8 meters becomes 13.6. Then, you subtract that from the total perimeter, this leaves you with 7 meters. Those 7 meters are the sum of both width sides added together, so all you have to do is divide 7 by 2 to get 3.5 meters as your width. Before I go on do you understand how I got that number?
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
</span>
