You want to find a common denominator and the easiest way to do this is to find the least common denominator which would be 36 in this case. To get the denominators to 36 you can multiply until you get a shared denominator. 12*3=36 and 9*4=36 so now you want your numerators to match so multiply by each corresponding number so 11*3=33 and 7*4=28 so you’d get something like 33/36-28/36=5/36 which would be your answer. Sorry if this is wrong, it’s been a while since I’ve done this.
Answer:
44
Step-by-step explanation:
use the order of operations
5 (3) 2 + 3 + 11. solve within parenthesis
15 × 2 + 3 + 11. multiply left to right
30 + 3 + 11. multiply left to right
33 + 11. add left to right
44. add
the order of operations is more commonly known as PEMDAS.
(parenthesis, exponents, multiply and divide, add and subtract)
If you are still confused there is a Brain Pop about PEMDAS. just search "order of operations" on the brain pop website
Answer:
tan(C) = 3/4
Step-by-step explanation:
If the sine of angle C is 3/5 and we want to find the tangent of the angle C, we can first find the cosine of angle C using the following equation:
Then, we can find the tangent relation using the equation:
T = 2.5h
l = t + 1.6
l = 2.5h + 1.6
5.2 = 2.5h + 1.6
5.2 - 1.6 = 2.5h
3.6 = 2.5h
3.6 / 2.5 = h
1.44 = h <===== length of head is 1.44 meters
Answer: choice #2, or −3(x − 1)(x − 3)(x + 4)
Explanation:
The first three points are zeros (or roots) of the polynomial (1, 0), (3, 0), (−4, 0).
They imply factors (x-1), (x-3) and (x+4) and can be easily check against the factorized forms in the four choices. They allow us to narrow the choices to the first two.
Then we use the point (0,36), setting x=0 to determine the value y. In the first choice the value is -36, in the second choice it is 36, therefore the answer is choice #2.
