Answer:
Step-by-step explanation:
I'm just going to go out on a limb here and assume that those are a set of poorly made parenthesis. This, then, would be your equation:
The first thing to do is distribute through the parenthesis to get:
Next is to get rid of the denominators by multiplying by the LCM of 77:
which gives you:
77x + 11x + 7x + x = 4620 and
96x = 4620 so

29) First of all when I write “^2” I mean to the power of 2. Label the bottom line Z or whatever u fancy. Then make 3 equations to solve simultaneously using a^2+b^2=c^2
(1) 14^2+y^2=Z^2
(2) 6^2+y^2=x^2 and (3) x^2+z^2=20^2
The next step is to solve them simultaneously e.g you can rearrange (2) to give you y^2=x^2-6^2 and then input that into (1) to get 14^2+x^2-6^2=Z^2 and again you rearrange (3) to get z^2=20^2-x^2 and input that in and solve for x. Then you will have to repeat that solving for y and only y as the question doesn’t originally ask for z but only for the values of x and y I assume. Using this idea, from glancing at the other questions you should be able to apply this concept to those other questions, if not then make another post outlining any specific questions
The formula for area of a circle is Area = PI x r^2
The radius (r) is given as 9 meters.
The value of PI is given as 3.14
Area = 3.14 x 9^2
Area = 3.14 x 81
Area = 254.34 m²
