Answer:

B -9(9x-3)

Step-by-step explanation:

b/c -9(9x-3) means -9×9x-(-3)

= -81x+27

if you say why -(-3) is +27, I will say b/c negative times negetive it give us positive. and if you they why we don't add -81x and 27, I will say b/c they are not like terms.

like terms : are terms with the same variable and same exponent.

example:2x and 3x,5xy and 9yx and etc....

if it helpful ❤❤

A power lifter is leg-pressing 720 pounds on a leg press machine. The angle of the press is 60 degrees. What is the actual weigh
Triss [41]

Since, the angle between the machine and angle of press is 60^{\circ} as shown in the attached image.

Therefore, the actual weight lifted by the power lifter is given by w \times \cos \Theta

where 'w' stands for the weight being lifted and \Theta is the angle of press.

Now,

actual weight lifted by the power lifter = 720 \times \cos 60^{\circ}

= 720 \times \frac{1}{2} = 360 pounds.
