Answer:
-14
Step-by-step explanation:
Multiply the is together. Multiply the j's together. Add the answer. The answer is a scalar.
(7 × -2) + (5 × 0)
= -14
0.85. If something is 15% off, you will pay. 85% of the price, since 100-15=85.
Use SOH CAH TOA
sin(x) = opp/hyp
cos(x) = adj/hyp
tan(x) = opp/adj
sin(x) = 3.9/8.1
sin(x) = 0.481
Inverse sin of 0.481 = 28.8 degrees
Each answer should be between 0 and 90 :)
Answer:
Step-by-step explanation:
its c
24a ^ 2-6a-9.
you should do in this case is to see the terms that are repeated in the expression.
WE have then that the terms are a and the multiples of 3.
Making a common factor we have:
24a ^ 2-6a-9.
3 (8a ^ 2-2a-3).
3 (a (8a-2) -3)
Answer:
The equivalent expression is:3 (a (8a-2) -3)
