27 divided by 9 = 3
3 X -7= -21
Answer:
The ladder reaches (4)(√3) ft up the wall (6.93 ft)
Step-by-step explanation:
Think of a triangle with a 60 degree angle in the lower left corner. The lower right corner is a right triangle, and 8 ft is the length of the hypotenuse. The other angle is 30 degrees.
We know the angle 60 degrees, plus the length of the hypotenuse, but need the length of the vertical side opposite the 60 degree angle. Use the sine function here because it involves these knowns:
opposite side
sin 60 degrees = ------------------------ = x/(8 ft) = (√3)/2
Cross-multiplying, we get:
2x = (8 ft)(√3), or through reduction, x = (4)(√3)
The ladder reaches (4)(√3) ft up the wall (6.93 ft)

Answer:
The correct answer is Option 2. 48
Step-by-step explanation:
The given equation is 3x² ---(1)
When we substitute the value of x we get the value of the equation.
Here it is given that,
x = 4
Substitute this value in the equation (1) we get,
3x² = 3*(4)² = 3*16 = 48
Therefore the correct answer is Option 2. 48
