Answer:
(7×2 + 4x + 10) - ( 3×2 + 2x - 6)
(14 + 4x + 10) - ( 6 + 2x - 6)
(4x + 14 +10) - ( 2x + 6 - 6)
(4x + 24) - ( 2x )
4x + 24 - 2x
4x - 2x + 24
2x + 24
Step-by-step explanation:
clear bracket
All multiplication , subtraction and addition
should be first done in the bracket
After clearing bracket,
then subtract the left answer from the right answer
To get your final answer
Answer:
4x^2 +2x +16
Step-by-step explanation:
7x2 + 4x + 10) - (3x2 + 2x - 6)
Distribute the minus sign
7x2 + 4x + 10) - 3x2 - 2x + 6
Combine like terms
7x2 + 4x + 10)
- 3x2 - 2x + 6
-------------------------
4x^2 +2x +16

Answer:
tan2(x) + 1 = sin2(x)/cos2(x) + 1 = [sin2(x) + cos2(x)]/cos2(x) = 1/cos2(x) = (1/cos(x))2 = sec2(x). Thus tan2(x) + 1 = sec2(x).
Step-by-step explanation:
The area is 128
multiply the base by the height, and then divide by 2.
the base is 16 and the height is also 16 so 16x16 is 256 divided by 2 is 128
