Answer:
Step-by-step explanation:
We will use order of operations to simplify this expression.
We will evaluate the brackets first.
3(5+7)-6(4-2x) =
You can further simplify it by factorising it:
Answer:
1.5
Step-by-step explanation:
of the similar shapes you are only given the lengths of two corresponding sides, 22mm and 33mm
if you do 33/22 you get 1.5 so your scale factor is 1.5
(in order to go from the original shape to the copy times by 1.5, and divide if you know the length of the copy and want to work out the original)
The equation to find the volume of a cylinder is
(pi)(r^2)(H)
we have the volume and radius
78.5 = (3.14)(2.5^2)(H)
78.5 = 3.14 * 6.25 * H
78.5 = 19.625H
/19.625 /19.625
4=H
The height of the cylinder is 4 meters
Answer:
6082.12
Step-by-step explanation:
well the equation of an area of a circle is is pie*R^2
so it could be 3.14*44^2 which honestly would not complete to any of your answers i googled the equation and it said it was 6082.12 it shows you how to do it too.
please look at it ill leave the website

Or you look up area of a circle and a converter to show up thanks
Answer:
<em><u>x = -0.5</u></em><em> </em>
Step-by-step explanation:
<em>You need to combine like terms</em>
x * 2 + 5x = -6
<em>Add x to 5x</em>
6x * 2 = -6
<em>Divide 2 from both sides</em>
6x = -3
<em>Divide 6 from both sides to get x alone</em>
x = -0.5
<em>Hope this helps</em>
