Add 6x and x to have 7x.
-1+6x+x=-1
7x-1=-1
+1=+1
7x=0

Divide 7x by 7 so the x can be left alone.

X=0

First you combine the x. 6x+(1)x = 7x
-1+7x=-1

Then move the -1 to the other side, changing the sign( if it is positive make it negative. If it is negative make it positive) -1+1 = 0
7x=0

Next you divide the 7 by 0 because you undo the multiplication ( the opposite of multiplication is division) 7/0 = 0
x=0

Hope this helps!!❤️

Akimi4 [234]

Answer:

24

Step-by-step explanation:

A triangle is a three sided polygon with three edges and three vertices

There are different types of triangles. They include :

  • Right angled triangle - one of the angles measure 90 degrees
  • equilateral triangle - all three sides of the triangle are equal
  • isosceles triangle - two sides of the triangle are equal

Area of a triangle = 1/2 x ( base x height)

1/2 x (6 x 8) = 24 ft²

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.
stich3 [128]

Mario says that the expression 4+3n^2 has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

4+3n^2

Given that, Mario says that the above expression has four terms

But Mraio is incorrect

Because the given expression has two terms only

4 is one of the term

3n^2 is another term

So there are totally 2 terms only

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

Here 3 is a constant multiplied by n^2

So, 3n^2 is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression

What is the missing constant term in the perfect square that starts with x2 – 12x ?
Dima020 [189]

Answer:

x^2 -12x+36

Step-by-step explanation:

x^2 – 12x

Take the coefficient of x

-12

Divide by 2

-12/2 = 6

Square it

6^2 = 36

We need to add 36 to make x^2 -12x a perfect square trinomial

x^2 -12x+36
