The area of a rectangle if the length is 5 more than 4 times the width, what's the algebraic expression for this question ​

Answers

A= 4w+5

Please mark brainliest

The area of a rectangle if the length is 5 more than 4 times the width, the algebraic expression for this is, A = (4b + 5) × b

What is the area?

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

The length is 5 units more than 4 times the width

Suppose,

length = l

width = b

So, according to given condition

l = 4b + 5

Now, the area for rectangle is

A = length × width

A = l × b

A = (4b + 5) × b

Hence, the algebraic expression is (4b + 5) × b

For this problem, b is the y-intercept.

On the graph, the line intersects the y-axis at (0, 10).

That means b is 10.

For the slope, we need to find the rise over run of the line. We see that the line goes up 2 and over 4. This simplifies to [tex]\frac{1}{2}[/tex].

That means m is [tex]\frac{1}{2}[/tex].

The length of a rectangle is 9 centimeters more than half
the width. Find the length if the perimeter is 60 centimeters.

Answers

Answer:

l = 16 cm

Step-by-step explanation:

Let's set the width of the rectangle as "w" and the length of the rectangle as "w/2 + 9".

The perimeter of a rectangle is calculated by adding up the value of all of its side lengths. Therefore, we can find the perimeter using 2l + 2w = P.

We can substitute 60 for P and w/2 + 9 for l.

2(w/2 + 9) + 2w = 602w/2 + 18 + 2w = 60 w + 18 + 2w = 603w + 18 = 603w = 42w = 14

Substitute w = 14 into the equation for length l.

l = w/2 + 9 l = 14/2 + 9 l = 16

The length of the rectangle is 16 cm.

Answers

Answer:

Length = 7cm

Breadth = 4cm

Step-by-step explanation:

The shape of the room is original my in a square shape

Area of a rectangle = Length × Breadth

Area = 28 cm²

Length = L - 1

Breadth = B + 2

Hence

28 = (L - 1)(B + 2)

b(b + 3) = 28

b² + 3b = 28

b² + 3b - 28 = 0

b² +7b - 4b - 28 = 0

Using the converse of Pythagoras' identity

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.

longest side = 17 and 17² = 289

9² + 12² = 81 + 144 = 225 ≠ 289

BAI BD
mZCBD = 40 +52
m ABC = 82 - 10°
Find mZCBD:
B
D

Answers

Answer:

m∠CBD=68°

Step-by-step explanation:

BA is perpendicular to BD, meaning they form a right angle (90°)

This means m∠CBD + m∠ABC=90, or they are supplementary.

We have expressions given for these angles, so

4x+52+8x-10=90

12x+42=90

12x=48

x=4

Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.

4(4)+52=68

m∠CBD is 68°.

A 26 foot ladder is set against the side of a house so that it reaches up 24 feet. If Mila
grabs the ladder at its base and pulls it 12 feet farther from the house, how far up the side of the house will the ladder reach now?

Answers

Answer:

13.9

Step-by-step explanation:

13.85 feet far up the side of the house will the ladder reach now.

Given that, a 26 feet ladder is set against the side of a house so that it reaches up 24 feet.

What is heights and distances in trigonometry?

In mathematics, you can calculate the height of an object using the distance and angles. Here distance is the horizontal distance between the object and the angle is the angle above the horizontal of the top of the object, which gives the height of the object.

Let the distance between base of house to foot of the ladder be x.

Using Pythagoras theorem 26²=24²+x²

⇒ 676 = 576 + x²

⇒ x² = 100

⇒ x =10 feet

Mila grabs the ladder at its base and pulls it 12 feet farther from the house.

Now, the distance between base of house to foot of the ladder = x+12

= 10+12 = 22 feet.

So, up the side of the house the ladder reach = 24-h

Then, 26² = (24-h)²+22²

⇒ 676 = (24-h)²+484

⇒ (24-h)² = 192

⇒ (24-h) = √192

⇒ (24-h) = 13.85

⇒ h = 24-13.85

⇒ h = 10.15 feet

Therefore, 13.85 feet far up the side of the house will the ladder reach now.
