35*36=1260

Step-by-step explanation:

Answer:

35, 36

Step-by-step explanation:

Let the two consecutive positive integers be x and (x + 1)

According to the given information:

[tex]x(x + 1) = 1260 \\ \\ {x}^{2} + x - 1260 = 0 \\ \\ {x}^{2} + 36x - 35x - 1260 = 0 \\ \\ x(x + 36) - 35(x + 36) = 0 \\ \\ (x + 36)(x - 35) = 0 \\ \\ x + 36 = 0, \: \: x - 35 = 0 \\ \\ x = - 36, \: \: x = 35 \\ \\ \because \: x \in \: positive \: integer \\ \\ \therefore \: x \neq \: - 36 \\ \\ \therefore \: x = 35 \\ \\ x + 1 = 36[/tex]

Answer:

19 is the numerical value

Step-by-step explanation:

Also, when it's converted to number I.e.

E = 14 , B = 11

= 14 + 11 = 25

But in letters the numerical value is

E + B = 19

Answer: -0.83

Step-by-step explanation:

A correlation coefficient(r) is used to determine the strength and direction of the relationship between two variables.

-1 ≤ r ≤1

For downward trend r is negative.

For strong correlation r should be closer to 1 or -1.

From the given correlation coefficients  -0.83 is both negative and closer to -1.

Hence, a correlation coefficient represents the strongest downward trend in a data set = -0.83

Answer:

[tex]x=-\frac{8}{19}[/tex]

Step-by-step explanation:

2(4x + 5) = 9(3x + 2)

Solve for x

___________________

We have an alrebaric expressio and are asked to solve for x, which to do this, we need to isolate x.

2(4x + 5) = 9(3x + 2)

Distribute :

(2(4x) + 2(5)) = (9(3x) + 9(2))

8x + 10 = 27x + 18

Subtract 10 from both sides :

8x = 27x + 8

Subtract 27x from both sides :

-19x = 8

8 = -19x

Divide both sides by -19 :

[tex]x=-\frac{8}{19}[/tex]

Answer:

Step-by-step explanation:

Pythagorean theorem,

Base² + altitude² = hypotenuse²

x² + 3² = 6²

x² + 9 = 36

      x² = 36 - 9

     x² = 27

x = √27

Answer:

D) x=sq rt 27

Step-by-step explanation:

using the Pythagorean theorem

6^2=3^2+x^2

36=9+x^2

27=x^2

x=sq rt 27

Answer: 5/8b + 4/5

EXPLAIN: It's too easy explain it yourself. (LOL)

The value of the equation is A = ( 5/8 )b + 4/5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = ( 2/8 )b + ( 3/8 )b + ( 4/5 )   be equation (1)

On simplifying the equation , we get

A = [ ( 2/8 )b + ( 3/8 )b ] + 4/5

A = ( 5/8 )b + ( 4/5 )

On further simplification , we get

A = ( 25b + 32 ) / 40

Therefore , the value of A is ( 5/8 )b + ( 4/5 )

Hence , the equation is A = ( 5/8 )b + ( 4/5 )

Answer:

x=1,y=2

-2x-4y= -10 maltiple by -1 then 2x +4y

-7x-4y= -15

therfore 2x+4y=10

-7x-4y=-15 to find x or y you must zero one of them

ther fore 4y-4y=0

then 2x+(-7x)= -5x

-5x=10 +(-15) =-5

-5x = -5

divide by -5 both side,

x =1

to get the value of y the value of x supersed in to equation

-2(1) -4y = -10

-4y =-10 +2

-4y = -8 both dived by -4

y=2
