Answer:

29

Step-by-step explanation:

substitute 5 where the w goes in the expression.

It should look like  4 • 5 + 9

Using the order of operations ( PEMDAS ) multiply 4 • 5 to get 20 and then add 9 to get 29

Using the order of operations ( PEMDAS ), the value of the expression is 29.

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

We need to find the value of the expression below when w = 5w = 5.

Using the order of operations ( PEMDAS ),

Then substitute 5 where the w goes in the expression.

4w+9 =  4 • 5 + 9

4w+9 = 20 + 9 = 29

Using the order of operations ( PEMDAS ), the value of the expression is 29.

The solutions to the given quadratic equation are (3+√5)/2 and (3-√5)/2.

Quadratic formula is the simplest way to find the roots of a quadratic equation.

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

The given quadratic equation is x²-3x+1=0.

By comparing x²-3x+1=0 with ax²+bx+c=0, we get a=1, b=-3 and c=1.

Now, x= [3±√((-3)² - 4×1×1)]/2×1

= [3±√(9-4)]/2

= (3±√5)/2

So, the solutions to the given equation are (3+√5)/2 and (3-√5)/2.

Therefore, the solutions to the equation are (3+√5)/2 and (3-√5)/2.

Answer:

i think its 66%

Step-by-step explanation:

Answer:

sqrt (2) * sqrt(45) + sqrt (2) * sqrt (80)

45 = 9 *5 "9" is a perfect square so

sqrt (45) = 3 * sqrt (5) * sqrt (2)

sqrt (2) * sqrt (80)

80 = 16 * 5  "16" is a perfect square so

sqrt (2) * sqrt (80) = sqrt (2) * 4 * sqrt(5)

Adding both answers we get

3 * sqrt (5) * sqrt (2) = 3 * sqrt(10)

PLUS

4 * sqrt (10)

which equals

Answer:

-2

Step-by-step explanation:

Note that slope-intercept form looks like: y = mx + b

In this case, isolate the y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides:

2x (-2x) + y = 6 (-2x)

y = -2x + 6

Note in the slope-intercept form: y = mx + b

y = y

m = slope

x = x

b = y-intercept

In this case, your slope is -2. All lines parallel to the given equation will also have a slope of-2.

Answer:

£5

Step-by-step explanation:

5 boxes will cose 5 x 15.40 = 77 normally.

according to the table, he will get 6.5% discount.

6.5 percent of 77 is 77x0.065 = 5.005 ≈ 5

Answer:

he orders 5 boxes of paperclips, that comes around to 77 dollars. That means he will get a 6.5 percent discount. So you would multiply 77 by .065 and you would get 5.005. You would take that number and subtract it by 77 and would get 71.995 and you can round that up to 72 dollars. My guess is that either 72 or 5.005 is the answer as 72 dollars is the price after the discount and 5.005 is how much he is saving

Answer:

length =√area use this formula

The side length of square can be found by taking the square root of Area.

Square are closed polygons which consist of four sides and four angles.

Each angle is 90 degree.

All the sides are of equal length.

So, by the definition of square, we know that the side lengths of square are equal.

The formula to calculate the area of the square is,

Area = a², where a is the length of one side of the square.

Let Area be given, let it be equal to A.

Then,

a² = A

Taking square root on both sides,

a = √A

Hence the side length is found by taking the square root of Area.
