plz help find perimeter and area

Answers

so I’m not sure what area is because I struggle with it too.
But perimeter is like adding all the sides together
so: 5x+2+X+8+5x+2+X+8
You collect all the terms which is 5x and X then that gives u 12x+2+8+2+8
Keep the 12x But add all the other numbers
so ur answer for perimeter would be
(12x+20)

I hope this helps for perimeter ❣️

What is the slope of a line perpendicular to the line of the equation in the above ? Please help answer !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

- 4

Step-by-step explanation:

Slopes of perpendicular lines are negative-reciprocals.If m is the slope of one line, the slope of the perpendicular line is -1/m.

Let's find the slope of the given line:

x - 4y = -12

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

x - 4y = -124y = x + 12y = 1/4x + 3

The slope is 1/4

The perpendicular line has slope

- 1/(1/4) = - 4

A group of friends are at a baseball game and are purchasing souvenirs. Olivia purchased 1 t-shirt and 5 baseball caps, spending a total of $165. Her Marco purchased 1 t-shirt and 4 baseball caps, which cost him a total of $137. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?

Answers

Answer:

baseball cap = $28

t-shirt = $25

Step-by-step explanation:

Olivia: t +5b = 165

Marco: t + 4b = 137

isolate t in Olivia's equation

t = 165 - 5b

plug t into Marco's equation

165 - 5b + 4b = 137

165 - b = 137

b = 28

plug b into either equation

t + 4b = 137

t + 4(28) = 137

t + 112 = 137

t = 25

An equation of a line that goes through -1/-3 and is parallel to the line 6x - y =1

Answers

Answer:

y=6x+3

Step-by-step explanation:

1.6x-y=1 solve for y

-y=-6x+1 divide bot sides by -1

y=6x-1

slope is 6

the slopes of parallel lines are equal

y-(-3)=6(x-(-1))

y+3=6(x+1)

y+3=6x+6

y=6x+6-3

y=6x+3

Answers

The required triangle PQS and triangle QRS are similar triangles. Option D is correct.

What are Similar triangles?

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.

According to the diagram,
It can be inferred that triangle PQS and triangle QRS are similar to each other. The term "similar" implies that these two triangles have the same shape but can be different in size. Specifically, the corresponding angles of these triangles are equal, and the corresponding sides are in proportion.

Consider triangle, PQS, and triangle QRS

Angle S is the common angle in both the triangles
And angle Q is similar to angle R

So both the triangle are similar by AA similarity postulate

Therefore, option D is correct.

14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6

Answers

Answer:

a = 4

Step-by-step explanation:

a = 4

If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.

Answer:

x can not equal zero, as it would cause division by zero.

Step-by-step explanation:

First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:

4x - 9 = ax + 6

If we solve for a, we get:

ax + 6 = 4x - 9

ax = 4x - 15

a = 4 - 15 / x

With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

The selling price of an item is $585. It is marked down by %20, but this sale price is still marked up from the cost of $360. Find the markup from cost to sale price.

Answers

Answer:

$108

Step-by-step explanation:

The selling price being marked down by 20% means that $585 was reduced by 20%

Selling price = $585 - ( 20% x $585)

$585 - (0.2 x $585) = $468

Markup from cost = selling price - cost price

$468 - $360 = $108

The solution of the equation is 17.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given an equation as;

(5x+17)+129+94+(7x-46)+(9x-11)=540

Solving;

5x+7x+9x+17+129+94-46-11=540

21x+146+94-57=540

21x+240-57=540
