F(6) = -(6)^2 + 6(6) - 4
= -36 + 36 - 4
= -4
A
5x + 10y = 360
y = 2x + 1
5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14
y = 2x + 1
y = 2*14 + 1
y = 29
Derek has 14 nickels and 29 dimes
-3x/2 + 5 would be equivalent.
Answer: the first option is the correct answer.
Step-by-step explanation:
Triangle ABC is a right angle triangle.
From the given right angle triangle,
AB represents the hypotenuse of the right angle triangle.
With m∠A as the reference angle,
AC represents the adjacent side of the right angle triangle.
BC represents the opposite side of the right angle triangle.
To determine the tangent of angle A, we would apply the Tangent trigonometric ratio. It is expressed as
Tan θ, = opposite side/adjacent side. Therefore,
Tan A = 5/5√3 = 1/√3
Rationalizing the surd, it becomes
1/√3 × √3/√3
Tan A = √3/3
Answer:
96 cm square is the area of the rectangle
Step-by-step explanation:
40 cm = 2 * 12cm + 2* x
= 24 cm + 2x
2x = 40 - 24
= 16
x = 8
Thus the length is 8 cm.
Therefore,
Area = 8cm * 12cm
= 96 cm square
