Answer:
84
Step-by-step explanation:
because the top and bottom lines are parallel, we can conclude that the 2 triangles (top and bottom) are similar triangles. This means the sides lengths of smaller triangle is proportional to the respective sides on the larger triangle. With this, we can form the following equation:
x/48 = 21/12 (multiply both sides by 48)
x = (21/12)· 48
x = 21 ·4
x = 84
Answer: The expression for a and y are not clear, however whatever expressions you are give, you can use the same approach as solved in the attached file.
At which x value is the tangent to this curve horizontal = 176/3
What is the total area inside the loop = 546.13 square unit
Step-by-step explanation:
The steps and appropriate derivation is as shown in the attachment.
Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!
Answer:
A because it cannot be simplified to anything smaller
Step-by-step explanation:
It can’t be simplified because 17 is a prime number
