Factorise fully 2x+8

Mathematics
2 answers:
madreJ [45]3 years ago
6 0

Answer: 2(x + 4)

Explanation: If you're asked to factor a polynomial,

the first thing you want to look for is the greatest common factor

for the terms that are involved.

The greatest common factor of 2x and 8 is 2.

So a 2 can factor out.

Inside the parenthses, we have each term divided by

the 2 that factored out of the polynomial.

So we have 2(x + 4).

Answer:

2(x+4)

Step-by-step explanation:

To factor you have to divide both terms by the greatest common factor, which in this case is 2. Using distribution you can check your answer.

When the points below are connected, they will form triangle ABC. Show and state whether this triangle has a right angle or not.
cluponka [151]

Answer:

See explanartions below

Step-by-step explanation:

Given the coordinates A(-6,3) B(0,5) C(2,-1)

We first need to get the slope of AB, BC and AC

For AB;

A(-6,3) B(0,5)

Mab = 5-3/0-(-6)

Mab = 2/6

Mab = 1/3

For BC;

B(0,5) C(2,-1)

Mbc = -1-5/2-0

Mbc = -6/2

Mc = -3

For AC:

A(-6,3) C(2,-1)

Mac = -1-3/2-(-6)

MAc = -4/8

Mac = -1/2

Taking the product of Mab and Mbc

Mab * Mbc = 1/3 + -3

Mab * Mbc = -1

<em>Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees</em>

2x-4y=8 and 7x-3y=61 solve by substitution
Ratling [72]

Answer:

(10, 3)

Step-by-step explanation:

Solve by Substitution

2x − 4y = 8 and 7x − 3y = 61

Solve for x in the first equation.

x = 4 + 2y 7x − 3y = 61

Replace all occurrences of x with 4 + 2y in each e quation.

Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61

x = 4 + 2y

Simplify 7 (4 + 2y) − 3y.

28 + 11y = 61

x = 4 + 2y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

11y = 33

x = 4 + 2y

 Divide each term by 11 and simplify.

y = 3

x = 4 + 2y

 

Replace all occurrences of y with 3 in each equation.

Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)

y = 3

Simplify 4 + 2 (3).

x = 10

y = 3

The solution to the system is the complete set of ordered pairs that are valid solutions.

(10, 3)

The result can be shown in multiple forms.

Point Form:

(10, 3)

Equation Form:

x = 10, y = 3

The diagram which the locus of all the points in the plane that are 3cm away from a single point A is Option B

<h3>What is a locus?</h3>

A locus is defined as a set of points, which satisfies a given condition or situation for a shape or a figure.

It is important to note that:

  • The locus of points in a plane that are all the same distance from a single point is a circle with radius, r
  • A circle is the locus of all the points in the plane which are equidistant from the points in that plane
  • The locus of all points equidistant from the vertices of a square is a straight line that is perpendicular to the plane of the square, through the center of the square

We can see that for a circle, the locus of all points in the plane is the radius equidistant from that line.

Thus, the diagram which the locus of all the points in the plane that are 3cm away from a single point A is Option B

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?
jekas [21]

The sum of the interior angles in the polygon whose side is 10 is 1440^{0}

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × 180^{0}

S0, n=10

Then, sum of interior angle be = (n-2) x 180

                                                   = (10-2) x 180

                                                   = 8 x 180

                                                   = 1440^{0}

Thus, the sum of the interior angles in the polygon is 1440^{0}
