Answer: 2t + -8

Step-by-step explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change this minus to plus a negative.

Now we can distribute or multiply this 2 times

each of the terms inside the set of parentheses.

So we get 2(t) + 2(-4) and this simplifies to 2t + -8.

2t + -8 is the same thing as 2t -8.

What is the mechanical advantage of the screw shown below?

algol13

Answer:

C. 8.0

Step-by-step explanation:

The mechanical advantage is got from dividing the circumference of the shaft by the pitch of the screw.

Therefore, the circumference= 2πr

=2×π×2.3mm

=14.45mm

Mechanical advantage=14.45mm/1.8mm

=8.03

You don't need the apothem if the side length is known, the area can be expressed as:

A(n,s)=ns^2/(4tan(180/n)), n=number of sides and s=side length so

A(7,28)=(7*28^2)/(4tan(180/7))

A≈2848.987 ft^2

A≈2849 ft^2 (to the nearest tenth of a square foot)

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

$x^2 = 6^2 + 8^2$
