anyone please help surds questions

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.

45 times ? gets you 45

? would be 1

45 times 1 equals 45.

45 times ? gets you 90

? would be 2

45 times 2 equals 90

45(1+2) = 45+90 = 135

♡ Hope this helps! ♡

Answer:

45(1 + 2)

Step-by-step explanation:

To find the greatest common factor, we find the multiples of 45 and 90.

45: 1, 3, 5, 9, 15, 45

90: 1, 2, 3, 5, 6, 9, 15, 18, 45...

The easier way to do this is divide 90 by 2 to get our GCF, 45.

We place the 45 (GCF) in the first box and we place 1 and 2 in the parentheses because when you distribute, we get our original answer.

45(1 + 2)

Answer:

x = 2

Step-by-step explanation:

Given

5x - 4 = - 3x + 12 ( add 3x to both sides )

8x - 4 = 12 ( add 4 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Answer:

A

Step-by-step explanation:

So we have the function:

[tex]f(x)=\frac{3+x}{x-3}[/tex]

And we want to find:

[tex]f(a+2)[/tex]

To do so, substitute in (a+2) for x:

[tex]f(a+2)=\frac{3+(a+2)}{(a+2)-3}[/tex]

Simplify the numerator and denominator. Add 2 and 3 in the numerator. Subtract in the denominator:

[tex]f(a+2)=\frac{5+a}{a-1}[/tex]

The answer is A.

Answer:

[tex]\Large \boxed{\mathrm{A}}[/tex]

Step-by-step explanation:

[tex]\displaystyle f(x) = \frac{3+x}{x-3}[/tex]

For f(a + 2), the input for the function f(x) is (a + 2).

Replacing x with (a + 2).

[tex]\displaystyle f(a+2) = \frac{3+(a+2)}{(a+2)-3}[/tex]

Simplify the rational function.

[tex]\displaystyle f(a+2) = \frac{(3+2)+a}{a+(2-3)}[/tex]

[tex]\displaystyle f(a+2) = \frac{5+a}{a-1}[/tex]

Step-by-step explanation:

6x-2=4x-4

-4x both sides

2x-2=-4

+2 both sides

2x=-2

divide by 2

x=-1

Answer:

2(3x-1)= 4(x-1)

Open bracket

6x-1= 4x-4

Group like terms

6x-4x= -4+1

Answer:

(x - 12)² + y² = 100

Step-by-step explanation:

The standard form of the equation of a circle is;

(x - a)² + (y - b)² = r²

where:

a and b are the coordinates of the centre of the circle

r is the radius

We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)

Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.

Coordinates of the centre is;

((22 + 2)/2), (0 +0)/2))

This is;

(12, 0)

So, a = 12 and b = 0

Now,to get the radius r, we will use the formula;

r = √[(x2 - x1)² + (y2 - y1)²]

Where;

(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)

r = √[(12 - 22)² + (0 - 0)²]

r = √(-10)²

r = √100

r = 10

Thus,equation of the circle is;

(x - 12)² + (y - 0)² = 10²

(x - 12)² + y² = 100

===================================================

Explanation:

Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify

[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]

Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means

x^2 = (-5)^2 = (-5)*(-5) = 25

but sticking a negative out front makes

-x^2 = -(-5)^2 = -25

Answer:

x = 75

Step-by-step explanation:

Triangle BDH

The angle must add to 180 degrees

36+ 39 + DHB = 180

75 + DHB = 180

DBH = 180-75

DHB = 105

DBH + x = 180 since it is a straight line

105+ x = 180

x = 75

Step-by-step explanation:

(x-4)^2 -28 = 8

This is a parabola on the left and a constant line on the right.  The parabola will cross the line twice, so there will be two solutions

see attached

Add 28 to each side

(x-4)^2 -28+28 = 8+28

(x-4)^2  = 36

Take the square root of each side

sqrt((x-4)^2) = ±sqrt(36)

x-4 = = ±6

Add 4 to each side

x-4+4 = 4±6

x = 4+6    x = 4-6

x = 10     x = -2

Answer:

x = 10, and x = - 2

Step-by-step explanation:

This equation has two solutions, as it resembles a quadratic equation. When graphed it will be a parabola, and hence intersects the x - intercept at two points, giving us two solutions.

Let's start by expanding the equation,

(x - 4)² - 28 = 8,

(x - 4)² = 28 + 8,

(x - 4)² = 36,

x - 4 = √36, and x - 4 = - √36

x - 4 = 6, and x - 4 = - 6

Solution(s) : x = 10, and x = - 2

Answer:

Her velocity is 95 km/hour

Step-by-step explanation:

The given information includes;

The direction to which Anna was driving = Eastward

Her initial location on the journey = 570 kilometres west of her her exit

The distance she drove in 2 hours = 1/3 of the way to her exit

Therefore, the distance she drove in 2 hours = 1/3×570 = 190 m

Her velocity = Her distance covered/(The time it take to cover the distance)

Which gives;

Her velocity = (190 km)/(2 hours) = 95 km/hour

Her velocity = 95 km/hour.

Answer:

90

Step-by-step explanation:

Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.

20 + 3(7 + 4) + 5 + 2(7+9)

20 + 3(11) + 5 + 2(16)

20 + 33 + 5 + 32

You can add those final four numbers in any order you want, to get a sum of 90.

Answer:

Your answer will be 90

Step-by-step explanation

First you will have to answer what's inside the parentheses

7 + 4 = 11 , 7 + 9 = 16

Then you multiply what is next to the parentheses

3×11 = 33, 2×16 = 32

Finally you will have to add

20 + 33 =53

53 + 5 =58

58 + 32 = 90

The point is doing PEMDAS
