Answer:
D 46x²+ 67x -16
Step-by-step explanation:
adding like terms
R1(x) + R2(x) = 16x²+52x-27 + 30x² + 15x + 11
total = 46x²+ 67x -16
They will each be 9.75 cm long
Hope this helps!
Answer:
Step-by-step explanation:
First move the numbers from the Left hand side to the right hand side. To do so, as it is an equation i.e. both sides must remain the same, you add or subtract the same numbers on both side.
5 + 13k - 61 = 17
5 - 5 + 13k - 61 + 61 = 17 - 5 + 61
13k = 73
k = 73 / 13
k = 5.62 (approximately)
Answer:
4
Step-by-step explanation:
The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in the circle, to one directly across)
In this case, the radius is 2.
So, 2 x 2 = 4.
The diameter is 4.
