Answer:

54.

Step-by-step explanation:

( 8 + √ 10 ) ( 8 − √10)

= 8*8  - 8√10 + 8√10  +√10 *  -√10

= 64 -  8√10 + 8√10 - 10

The 2 middle turns cancel out so we have:

64 - 10

= 54.

Answer:

Let n and n+4 be the numbers. Then:

n² + 3(n+4)=66

n²+3n-54=0

(n+9)(n-6)=0

n=6 or -9

n+4=10

Assuming positive integers only, the numbers are 6 and 10…..

Step-by-step explanation:

100% right

Natural number are those number that is used for the purpose of counting and ordering. The two natural numbers are 4 and 6.

Natural number are those number that is used for the purpose of counting and ordering. It is denoted by 'N'.

Let the first number(bigger number) be 'a', and the smaller number be b.

As it is given that the first number is 4 more than the second number. Therefore, the equation can be written as,

a = b + 4

Now, it is given that the product of the two numbers is three times the square of the smaller number. Since, when we add four to b we get a, therefore, b is the smaller number. Therefore, the equation can be written as,

[tex]ab = 3(b^2)\\[/tex]

As the value of a = b+4, substitute the value of a,

[tex](b+4)b = 3(b^2)\\\\(b+4) = \dfrac{3b^2}{b}\\\\b+4 = 3b\\\\4=3b-b\\\\4=2b\\\\b = 2[/tex]

Thus, the value of b is 2.

In order to get 'a' add 4 to the value of b, therefore, the value of a is,

[tex]a = b+4\\\\a = 2+4 \\\\a=6[/tex]

Hence, the two natural numbers are 4 and 6.

Answer:

2.478x10^7

Step-by-step explanation:

They give you each radius, so you just add them together.

15,300,000+9,480,000=24,780,000 = 2.478x10^7

(or)

1.53x10^7+0.948x10^7= 2.478x10^7

The sandwich will cost $3.1.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Let's say the cost of 1 drink is d while the cost of 1 sandwich is s

Now,

Given that,

A drink and a sandwich together cost $4.85.

So,

s + d = 4.85

And,

The sandwich cost $1.35 more than the drink.

So,

s = 1.35 + d

By using substitution

s = 1.35 + 4.85 - s

2s = 6.2

s = 3.1

Hence "The sandwich will cost $3.1".

Answer:

[tex]\huge\boxed{\sf Solution\ Set = \{x,y\} = \{1,2\}}[/tex]

Step-by-step explanation:

3x + 4y = 11 ----------------------(1)

x = 15 - 7y   ----------------------(2)

Put Eq. (2) in (1)

3(15 - 7y) + 4y = 11

45 - 21y + 4y = 11

45 - 17y = 11

Subtracting 45 to bot sides

-17y = 11 - 45

-17y = -34

Dividing both sides by -17

y = -34 / -17

y = 2

[tex]\rule[225]{225}{2}[/tex]

Put y = 2 in Eq. (2)

x = 15 - 7(2)

x = 15 - 14

x = 1

[tex]\rule[225]{225}{2}[/tex]

Solution Set = {x,y} = {1,2}
