The value of x is 3.8
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>

We have to solve the equation for "x"
Move the terms so that you end up with only terms involving x on one side of the sign and all the numbers on the other
Therefore, we get
x + 7.4 = 11.2
When we move 7.4 from left side to right side of equation it becomes -7.4
x = 11.2 - 7.4
Subtract 7.4 from 11.2
x = 3.8
Thus value of x is 3.8

is equation of circle which have radius equal 5 and center in (0,0) point
Answer:
3s + 3t
Step-by-step explanation:
To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:
(s + t) * 3 =
3s + 3t
And that is the simplified form for this expression.
Hope this helps :)
Answer:
36
Step-by-step explanation:
Square roots have a neat property:
provided <em>a</em> and <em>b</em> are positive real numbers.
This property is what's behind simplifying square roots. You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.
Example:
.
In this problem, both factors are perfect squares.
