8a+12b because you multiply 2 by each number. For example 4a times 2 is 8a and 6b times 2 is 12b
Hope that helped :)
Answer:
(28 x 14) + (36 x 15)
Step-by-step explanation:
the x is multiplication
Rate of change between 1 and 3: find the y values for 1 and 3:
Rate of change = (6-1) / (3-1) = 5/2
Rate of change from 2 and 4:
= (10-3) / (4-2) = 7/2
The rate from 2 to 4 is larger because 7/2 is larger than 5/2
Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) = 
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 = 
Now, switch the sides to make it easier.
= 0.8097
Multiply both sides by 25.
x = 20.24
