Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24
This is an incorrect question, the correct question is given below.
Martin is building a model. He cuts two pieces of wood that are each inches long from a board with a total length of 18 inches. What is the length, in inches, of the remaining part of the board?
Answer : The length of the remaining part of the board is inches.
Step-by-step explanation :
As we are given that:
Total length of the board = 18 inches
Length of each piece of wood cut from the board = inches = inches
Length of 2 pieces of wood cut from the board = inches
= inches
Length of the remaining part of the board = Total length of the board - Length of 2 pieces of wood cut from the board
Length of the remaining part of the board = inches
= inches
= inches
= inches
Therefore, the length of the remaining part of the board is inches.
Answer:
should be the third (81,90)

Answer:
5
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
With reference angle 30°
Perpendicular (p) = 5 cm
hypotenuse (h) = x = ?
Now
sin 30° = p / h
0.5 = 5 / x
x = 5/ 0.5
Therefore x = 10
