The perimeter of the rectangle is P = 6 + 2b, where b is the width.
Given data:
To find the perimeter of a rectangle, we add the lengths of all its sides. In this case, the rectangle is 3 meters long and b meters broad.
The perimeter is calculated as follows:
Perimeter = 2 × (length + breadth)
Given that the length is 3 meters and the breadth is b meters, substitute these values into the formula:
Perimeter = 2 × (3 + b)
Simplifying the expression,
Perimeter = 6 + 2b
Hence, the perimeter of the rectangle is 6 + 2b meters.

HOW CAN YOU USE SUBTRACTION TO DESCRIBE DIVISION? GIMME AN EXAMPLE PLS :(
Answer:
By repeated subtraction.
Step-by-step explanation:
It is pretty much the same thing as division, but in subtraction. Since, Dividing and Subtraction are a like, repeated subtraction is a great example to use for this example
Hope this helps. :)
Answer:
kk so like, division is just repeated subtraction. like idk say you have 36 and you divide it by 9 so I think you just keep subtracting 9 until you reach 0? so you end up subtracting 9 four times which happens to be the quotient for 36/9. yeah. it's almost like how multiplication is just repeated addition.

Answer:
9.9cmStep-by-step explanation:
The hemisphere will have its greatest radius along the diagonal of the cube it was surmounted on. The base of the cubical block will be square in nature. Since a cube has all its sides equal, we can find the length of its diagonal using pythagoras theorem as shown.
[tex]hyp^{2} = adj^{2} +opp^{2}[/tex]
Note that the diagonal will be the hypotenuse of the square face which is the longest sides.
Given adjacent = 14cm and opposite = 14cm
[tex]hyp^{2} = 14^{2} +14^{2}\\hyp = \sqrt{196+196} \\hyp = \sqrt{392} \\hyp = 19.8cm[/tex]
The diagonal of the base of the cube is 19.8cm which is equivalent to the greatest diameter of the sphere.
The greatest radius that the hemisphere can have = 19.8/2 = 9.9cm

Length lWidth wHeight hApplication:Let's draw a figure to supplement a visual image to further understand what we need to find. Please refer to the attached image for reference. Please excuse the poor handwriting/drawing. It is also not to scale.
We know that there is a cubical block w/ side measurements of 14 cm. "Surrmounted" means on top. So a hemisphere (half of a sphere) is on top of our block.
If we take a look at our geometrical shape from the top-down angle, we can see that the top would just look like a circle within a square, as depicted in blue.
Labeling our measurements, we can see that the length, width, and height of our cubical block are equal to 14 cm due to the definition of a cube. This extends to the definition of a square as well, so the length and width of our square are also equal to 14 cm.
With the side of the square equal to 14 cm, we know that this is equal to the circle's diameter. So d = 14 cm. We can solve for the radius of the circle/hemisphere by substituting it into the radius formula:
[tex]\begin{aligned}r & = \frac{d}{2} \\& = \frac{14 \ \text{cm}}{2} \\& = \boxed{ 7 \ \text{cm}} \\\end{aligned}[/tex]
Answer:∴ the greatest radius that the hemisphere can have is equal to 7 cm. Any r > 7 cm would result in the hemisphere being over the edge of the cube.

If you want to increase the length of the side of a square by 30%, what fraction can be used as the
multiplier to find the length of the new side?
The fraction (13/10) can be used as the multiplier to find the length of the new side.
Suppose the length of the side of a square is x.
The new length of the side of the square after an increment of 30%
= x+ (30% of x).
What is the percentage?The percentage is the value per hundred.
So, 30% of x = 30*x/100 =0.3x
So, new length of the side = x+0.3x =1.3x
We can represent 1.3x as (13/10)x
This means we have multiplied the previous length by the fraction 13/10 in order to get an increment of 30%.
Thus, The fraction (13/10) can be used as the multiplier to find the length of the new side.

[tex]2x+3=5y[/tex]
[tex]2x=5y-3[/tex]
[tex]x=\frac{5y-3}{2}[/tex]
The equation for x in terms of y is x=(5y-3)/2.
The given equation is y=(2x+3)/5.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now the given equation can be rearrange to make x the subject as follows:
Cross multiply 5 to y.
That is, 2x+3=5y
⇒ 5y-3=2x
⇒ x=(5y-3)/2

Would the midpoint (2,2) be correct?
Answer: YES, Its correct.
[tex]M_x=\frac{-6+2}{2}=2\\\\M_y=\frac{-3+7}{2}=2\\\\M=(2,2)[/tex]
Answer:
(-2,2)
Step-by-step explanation:
The midpoint is the middle of the line. So, you can take it step-by-step and look at the individual numbers.
Between -6 and 2, that is 8 spaces. So, the middle would be four spaces from one of those numbers. Therefore, X-COORDINATE = -2
Between -3 and 7, that is 10 spaces. So the middle would be 5 spaces from one of those numbers, Therefore, Y-COORDINATE = 2
So, the midpoint would be (-2,2)
