The factor outside the parentheses is -1. Distribute using that factor.
2 - (4 - <em>x</em>) = 7<em>x</em> - 5<em>x</em>
<em />
-1 * 4 = -4 and -1 * -<em>x</em> = <em>x</em>
<em />
2 - 4 + <em>x</em> = 7<em>x</em> - 5<em>x</em>
Simplify.
-2 + <em>x</em> = 2<em>x</em>
<em>x</em> = 2<em>x</em> + 2
-<em>x</em> = 2
<em>x</em> = -2
<h3>
Answer:</h3>
<em>x</em> = -2
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,

For a cube the surface area is
.
So the side is 1.0 inch in, the surface area is
square inches.
In Linear approximation means you ignore the term
, if
is a small number, because then
will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,

So here, 
The error in the area is approximately,

So the error is 0.012.

35°</h2>
Step-by-step explanation:
This is an isoceles triangle
And as we all know an isoceles triangle has two equal base angles.
And we also know that the sum of all interior angles of the triangle is 180°
So based on this we can form an algebraic equation of solve for angke t (Let's do it :))

So the base angle is 35°
Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0 (x+11) = 0
x-4 = 0 x + 11 = 0
x = 4 x = -11
The zeros of the equation are -11 and 4
