If x=7cm what is the surface area of the geometric shape formed by this net

Answers

There are four rectangles and 2 squares.

Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________

Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2

TOTAL: 392+392 = 784 cm^2

Wow I should have realized the the 4 rectangles are the area as the two squares.

Good luck to you!

a (−4.5,1.75)


b(−4.25,1.5)

c(−4.5,1.5)

d(−4.75,1.75)

Answers

Use the second equation. Replace x with the answer choices and if it equals the y value than that is the answer:

Y = x + 6

-4.5 + 6 = 1.5

The answer would be C. (-4.5,1.5)

What is the LCM of 24 and 90?​

Answers

24,48,72,96,120,144,168,192,216,240,264...360

90,180,270,360

LCM of 24 and 90 is 360

---

hope it helps

Answer:

Step-by-step explanation:

Find the prime factorization of each number

24=2*2*2*3, 90=2*3*3*5

The LCM will be the product of highest occurring primes, in this case

2*2*2*3*3*5=360

So the LCM is 360
