Answer:
(C) - 3x²+6
Step-by-step explanation:
(2x²+3x-4) +(8-3x) +(-5x²+2)= 2x²<em>+3x</em><u>-4 +8</u><em>-3x</em>-5x²<u>+2 </u>= - 3x²+6
Answer:
B
Step-by-step explanation:
the area of a parallelogram is the length of one of the sides multiplied with the length of the height on this side.
so, in this case it is
4×5 = 20 cm²
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
The answer would be 17.8 hope this help you
