Answer:
a
Step-by-step explanation:
-5(x + 2) = -4x - 12 - x + 2
= -5x - 10
= -5(x + 2)
both sides are equivalent so there are infinite solutions
You have to do whats in the parentheses from left to right then subtract the answer you get by 20
(9x10) - (30+30)
90 - 60 = 30
8 x (12+5) -7^2
17
17-49
18 x -32
= -576.
You have to use pemdas for your check off
P=parentheses
E=exponet
M=multiplication
D=division
A=add
S=subtrabt
HOPE IM CORRECT
12 + 6x + 6x + 6y = 12 + 12x + 6y
The length of a curve <em>C</em> parameterized by a vector function <em>r</em><em>(t)</em> = <em>x(t)</em> i + <em>y(t)</em> j over an interval <em>a</em> ≤ <em>t</em> ≤ <em>b</em> is

In this case, we have
<em>x(t)</em> = exp(<em>t</em> ) + exp(-<em>t</em> ) ==> d<em>x</em>/d<em>t</em> = exp(<em>t</em> ) - exp(-<em>t</em> )
<em>y(t)</em> = 5 - 2<em>t</em> ==> d<em>y</em>/d<em>t</em> = -2
and [<em>a</em>, <em>b</em>] = [0, 2]. The length of the curve is then
