Answer:

-4x+y = -1

Step-by-step explanation:

-12x + 3y = -3

I am going to factorise 3 out from the left hand side of the equation.

3(-4x+y) = -3

Shift the 3 over to the right hand side and turn (×3) into (÷3).

-4x + y = \frac{-3}{3}

Evaluate.

-4x + y = -1

The following polynomial can be factored using the techniques of this lesson x^2-18
Papessa [141]

Answer:

(x+3\sqrt{2})(x-3\sqrt{2})

Step-by-step explanation:

The given expression is x^2-18.

The technique that can be used to factor this polynomial is the difference of two squares.

We rewrite the two expressions as;

x^2-(\sqrt{18})^2

Recall that;

a^2-b^2=(a+b)(a-b)

x^2-(\sqrt{18})^2=(x+\sqrt{18})(x-\sqrt{18})

x^2-(\sqrt{18})^2=(x+3\sqrt{2})(x-3\sqrt{2})

Find the perimiter now

that is right triangle so
when hpotonouse is c and hthe lgs are a and b
a²+b²=c²

given
leg is 8
hypotonuse is 13

8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105

find total perimiter
8+13+√105=21+√105

times 1/32 for scale

Steps for solving 3x + 18 = 54 are shown.
Lostsunrise [7]

C

By subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
