Which of these shapes have the same perimeter

Mathematics
1 answer:
Snezhnost [94]3 years ago
5 0

Answer:

A) B and C

Step-by-step explanation:

To find the perimeter, add up the lengths of all the sides.

For shape A: 16+16+1+1= 34

For shape B: 8+8+2+2= 20

For shape C: 5+5+5+5= 20

Shapes B and C both have a perimeter of 20. The answer is A, B and C.

I hope this helps!

What is the equation of the graph shown?​
OlgaM077 [116]

<em>Greetings from Brasil...</em>

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

<em>A = ΔY/ΔX</em>

<em>B = where the line intersects the Y axis</em>

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

<h2>F(X) = 2X - 3</h2>

Stickers come in packs of 5. Max buys 12 packs. He gave his three friends some stickers. They each receive the same number. He h
Butoxors [25]

Answer: 11 stickers each

Step-by-step explanation:

given data:

packs of stickers bought by mark = 12 ( 5 ) = 60 stickers

no of stickers left with mark = 27

= Total no of stickers – stickers remaining with mark

= 60 – 27

= 33 stickers

he gave his 3 friends equal number of stickers.

3x = 33

x = 11

number of stickers received by each friend is 11

A garden contains two square peanut beds. Find the length of each bed if the sum of the areas is 914ft squared and the differenc
garik1379 [7]

Answer:

The answer to your question is:

m = length of the smaller bed = 17 ft

l = length of the larger bed = 25 ft

Step-by-step explanation:

Data

A1 + A2 = 914

A1 - A2 = 336

A1 = l²

A2 = m²

Process

l² + m² = 914

l² - m² = 336

l² = 336 + m²

(336 + m²) + m² = 914

336 + 2m² = 914

2m² = 914 - 336

2m² = 578

m² = 578 / 2

m² = 289

m = 17 ft

l² = 336 + 289

l² = 625

l = 25 ft

Why can’t we use the rules for exponents when the bases are not common?
Kazeer [188]

Answer:

Ok, the rules of the exponent come from a logic construction.

If we have x^n

this means that n is multiplied by itself n times.

If we decompose n into a + b, we have:

x by itself a times, and then x by itself b times, and for how the product works, this is equivalent:

if n = 5, a= 2 and b = 3

x^5 = (x*x*x*x*x)   5 times-

x^5 = x^(2 + 3) = (x^2)*(x^3) = (x*x*)*(x*x*x) = x*x*x*x*x = x^5

And the same for the other rules:

(x^n)^b = x^n*b and such.

Obviusly, this only works when we have a common base.

So the correct answer is that we constructed the exponential rules in a way that only can be used when we have a common base, and this happens because to construct them, we started with common bases.
