The product of the Expression is 3/ (a-2).

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows:

(Number/variable, Math Operator, Number/variable) is an expression.

We have,

(2a - 7)/ a x (3a²)/  (2a² -11a + 14)

Now, simplifying the expression as

(2a - 7)/ a x (3a²)/  (2a² -11a + 14)

= (2a - 7)/ a x (3a²)/  (2a² -7a - 4a + 14)

= (2a - 7)/ a x (3a²)/  a (2a -7) -2 (2a- 7)

= (2a - 7)/ a x (3a²)/ (a- 2)(2a-7)

= 3a² / a(a-2)

= 3/ (a-2)

Thus, the product is 3/ (a-2).

Step-by-step explanation:

The slope is 4/3

Answer:

17 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 30 × 90° = 2700° , then

180° (n - 2) = 2700° ( divide both sides by 180° )

n - 2 = 15 ( add 2 to both sides )

n = 17

Answer:

17 sides

Step-by-step explanation:

-Let the number of sides of the polygon be n

The sum of the interior angles of a polygon of n sides is.180° (n−2)

The sum of interior angles =30×90°

30×90° =180°(n−2)

15=n−2

n=17

Answer:

none just divide and get 12.57

This doesn’t make since

Step-by-step explanation:

y= 80 because alternate angles are equal

80+57=137

180-137= 43 because angles in a triangle add up to equal to 180

z= 43

180-80= 100

the angle P is 90 so 100+80+90=270

360-270=90 as the sum of the angles in a quadrilateral its 360

so

x= 90

y= 80

z= 43

AB=9m and BC=3m

Using Pythagoras theorem, In ΔABC

(AC)² +(AB)² +(BC)²

⇒(AC)² =(9)² + (5)²

⇒(AC)² =81 + 25

⇒(AC)² =106

⇒AC=10.3m

=AC+CB=10.3+3=13.3m

l = length

w = width = 15 ft

l = 2×w + 4 = 2×15 + 4 = 30 + 4 = 34 ft

the area of a rectangle is

area = l × w = 34×15 = 510 ft²

Question 1: Given [tex]1/10p=p-279[/tex] find [tex]p[/tex]

Answer:

[tex]p=310[/tex]

Step-by-step explanation:

1. Subtract [tex]p-279[/tex] from both sides: [tex]279-\frac{9p}{10}=0[/tex]

2. Subtract [tex]279[/tex] from both sides: [tex]\frac{9p}{10}=-279[/tex]

3. Multiply both sides by reciprocal [tex]\frac{10}{9}[/tex]: [tex]p=310[/tex]

Question 2: Given [tex]1/2p=p-155[/tex] find [tex]p[/tex]

Answer:

[tex]p=310[/tex]

Step-by-step explanation:

1. Subtract [tex]p-155[/tex] from both sides: [tex]155-\frac{p}{2}=0[/tex]

2. Subtract [tex]155[/tex] from both sides: [tex]-\frac{p}{2}=-155[/tex]

3. Multiply both sides by reciprocal [tex]\frac{2}{1}[/tex]: [tex]-p=-310[/tex]

4. Multiply both sides by [tex]-1[/tex]: [tex]p = 310[/tex]

5/3 (a)(x)(b)(xx)(c)(a^3)

5/3 (a^4)(b)(c)(x^3)

-2.07 (a^2)(x^3)(a^2)(b)

-2.07 (a^4)(b)(x^3)

-7/6 (a^2)(x^3)(c)(a^2)(b)

-7/6 (a^4)(b)(c)(x^3)

Notice that only the first and third monomials (when simplified) contain the exact same variables with the same exponents. Therefore, those are the only two monomials we can add together.

(10/6 - 7/6)(a^4)(b)(c)(x^3) - 2.07(a^4)(b)(x^3)

(1/2)(a^4)(b)(c)(x^3) - (2.07)(a^4)(b)(x^3)

(a^4bx^3)(1/2c - 2.07) --- Factored form

Since this expression has two terms, it is a binomial.

- All rhombuses are parallelograms

- Not all parallelograms are rhombuses because a rhombus has four equal-length sides and a parallelogram has equal opposite sides.

[tex]y = {(x - 3)}^{3} [/tex]

Step-by-step explanation:

The graph is indeed cubic and because y is 0 at 3 that means the graph is shifted to the right 3 units, so to write that as an equation we put -3 in the parentheses with the x. Also because it's a cubic graph the domain and range is infinite. If you read the statement above the chart it says a continuous graph. the chart is there to help identify the type of graph not to identify the domain and range

Answer:

the answer is 46.278

Step-by-step explanation:

the formula to find perimeter is πR + d

Answer:

-3 = -2

Step-by-step explanation:

3 (x + 1) - 6 = 5x - 2 (1 + x)

3x + 3 - 6 = 5x - 2 - 2x

3x - 3 = 5x - 2 - 2x

3x - 3 = 3x - 2

= -3 = -2
