Step-by-step explanation:
t^2-4xt-12/t-8
= -(t^2-4-6)/4
= -t^2+4+6/4
=<u> -t^2+6</u>
Answer:
51/56
Step-by-step explanation:
When dividing two fractions, you can get the same result by multiplying the first fraction by the reciprocal of the second fraction.
So,
17/28 ➗ 2/3 can be rewritten as:
17/28 ❌ 3/2
Then, simply multiply the numerators and the denominators together.
17*3=51
28*2=56
So, the answer is 51/56.
This fraction is already in its simplest form, so it cannot be reduced.
Area of semicircle is given by:

r is the radius, and we are given the diameter. Radius is half the diameter, so it's 2.5m. Let's plug that into the formula (using 3.14 as an estimation for pi):

So, the area of this semicircle is
9.81m².
