Answer:

52 m²

Step-by-step explanation:

The prism has 6 rectangular faces.

Opposite faces are congruent, that is

top/bottom, front/back and sides

A = 2(4 × 3) + 2(3 × 2) + 2(4 × 2)

=( 2 × 12) + (2 × 6) + (2 × 8)

= 24 + 12 + 16

= 52 m²

To get the answer type 2•4•3+2•4•2+2•3•2

in to a calculator And you’ll get “52m”

Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that $a^2+b^2=c^2$

Therefore, $12^2-6^2=CB^2$

$CB=\sqrt{108}$ (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

$Sin55=CB/CD\\Therefore, CD= 12.686$

5.b) If z^(1/2)=x^(1/2)+y^(1/2) , show that (x+y-z)^2=4xy

Rudik [331]

Answer:

Step-by-step explanation:

(x+y-z)²= 4xy
(x+y-z)²- 4xy = 0
(x+y-z)²-(2√x√y)² = 0
(x+y-z-2√x√y)(x+y-z+2√x√y) =0
[(√x-√y)²-z]*[(√x+√y)²-z]=0
(√x-√y)²-z = 0 or (√x+√y)²-z = 0

We have : z^(1/2)= x^(1/2)+y^(1/2) ⇒ √z = √x + √y ⇒ z = (√x + √y)²

so (√x+√y)²-z = 0

so (x+y-z)²= 4xy

3x < −2x + 7

Hunter-Best [27]

Answer: B

Because...
3x + 2x < -2x + 2x + 7
5x < 7
So you have to do addition BEFORE division.
