Answer:
The perimeter is 28.13 cm
Step-by-step explanation:
We connect a line from A to C
we can use the cosine rule to find the length AC
let us call it x
AC^2 = AB^2 + BC^2 - 2(AB)(BC) cos B
we have this as;
x^2 = 6^2 + 8^2 - 2(6)(8) cos 95
x^2 = 36 + 64 + 8.37
x^2 = 108.37
x = √108.37
x = 10.4 cm
AC = 10.4 cm
now, let us look at triangle ADC Where we have AC as the hypotenuse as it is the side facing the right angle
We can use Pythagoras’ theorem to get the value of CD
We have it that the square of the hypotenuse AC is the sum of the squares of the two other sides
let DC be y
10.4^2 = 5^2 + y^2
y^2 = 108.37 - 25
y^2 = 83.37
y = √83.37
y = 9.13 cm
The perimeter of the shape is the sum of all its sides
so we have;
AB + BC + CD + AD
= 6 + 8 + 9.13 + 5
= 28.13 cm

1.How do you know you have a direct variation in the
relationship between two quantities?
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.
Step-by-step explanation:
X - y = 4
X + y =8

9. Factorize: 6x2 - 19x + 14.
Answer:
Step-by-step explanation:
Here, we want to factor the given polynomial
We have this as;
6x^2 - 19x + 14
= 6x^2 -12x-7x + 14
= 6x(x-2) -7(x-2)
= (6x-7)(x-2)
6x^2-19x + 14 = (6x-7)(x-2)

write the linear equation given :
1. slope = 1/4; y-intercept =7
2. slope = -3; y-intercept = 2/3
3. slope = 2/3; y-intercept = 2/3
4. slope = -2; y-intercept = -1/2
5. slope = -3/4; y-intercept = -3
Answer:
Step-by-step explanation:
1. y = 1/4 x + 7
2. y = -3 x + 2/3
3. y = 2/3 x + 2/3
4. y = -2 x - 1/2
5. y = -3/4 x - 3
Solve the system of linear equations by substitution.
3x + y = -3 -2x + y =7
Answer:
(-2, 3)
Step-by-step explanation:
First solve one equation for y:
[tex]-2x+y=7\\y=7+2x[/tex]
Now we can substitute this equation into the other one:
[tex]3x+7+2x=-3[/tex]
Solve for x:
[tex]x=-2[/tex]
Now substitute this value into the equation [tex]y=7+2x[/tex]:
[tex]y=7+2x(-2)[/tex]
Solve for y:
[tex]7=3[/tex]
Now your solution is (-2,3)

aMath In comparison 1/3 to where 2/6 would be located on a number line closer to O B. the same point closer to 1 D. At O
Answer:
o represent 1/3 on a number line, we divide the gap between O and A into 3 equal parts. Let T and Q be the points of division. Then, T represents 1/3 and Q represents 2/3, because 2/3 means 2 parts out of 3 equal parts as shown below. By using the same procedure, point O represents 0/3 and point A represents 3/3.

Shea wrote the expression 5(y+2)+4 to show the amount of money five friends paid for snacks at a baseball game.Which espression is equivalent to the one shea wrote?
Answer: B. 5 ∙ y + 5 ∙ 2 + 4
Step-by-step explanation:
The options are:
a. 5 + y + 5 + 2 + 4
b. 5 ∙ y + 5 ∙ 2 + 4
c. 5 ∙ y + 5 ∙ 4 + 4
d. 5 ∙ y + 5 + 2 + 4
To solve the question, we have to expand 5(y+2)+4. This will be:
= (5 × y) + (5 × 2) + 4
= 5 ∙ y + 5 ∙ 2 + 4
= 5y + 10 + 4
= 5y + 14

Find the perimeter of the following shape (show all work and box your final answer):
=========================================
Work Shown:
To find the perimeter, we add up all the exterior side lengths.
P = perimeter
P = (side1) + (side2) + (side 3)
P = (2y-3x-3) + (12+5x+7y) + (9x-3y+2)
P = (-3x+5x+9x) + (2y+7y-3y) + (-3+12+2)
P = 11x + 6y + 11

Find the value of x
12
5
X
Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13
~
Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²
What is the rate of change of the table shown?
Answer: rate of change = 2
===============================
Explanation:
Apply the slope formula. I'll use the first two columns as the two points, but you can use any two columns you want.
m = (y2-y1)/(x2-x1)
m = (9-5)/(3-1)
m = 4/2
m = 2
The slope is 2, so the rate of change is 2. Slope and rate of change describe the same thing. Each time x goes up by 1, y goes up by 2.
