The 2nd one would be 476 square centimeters. You would multiply 14 by 10 and then divide by 2 for a triangle. When you add up the area for all 4 triangles it equals 280. You would then multiply 14 by 14 for the square to get 196. When you add 280 and 196 you get 476.

What ratio forms a proportion with 14/42?<br> A. 1/4<br> B. 7/21<br> C. 12/40<br> D. 28/80

koban [17]

Hey there!

"What ratio forms a proportion with $\frac{14}{42}$ ?"

- $\frac{14}{45} =0.56$ (for the decimal)

$A) \frac{1}{4}$ $=0.25$ $(incorrect)$
$B) \frac{7}{21}$ $=0.33$ $(Incorrect)$
$C) \frac{12}{40}$ $0.3$ $(incorrect)$
$D) \frac{28}{80}$ $0.7$ $(incorrect)$

But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)

$1\times2= 2$ ; $4\times2 = 8$ $(incorrect)$
$7\times 2= 14$ ; $21\times2 = 42$ $(correct)$
$12 \times2 = 24$ ; $40\times 2 = 80$ $(incorrect)$
$2 \times 28 = 56$ ; $2\times 80 = 160$ $(incorrect)$

Your result: $\boxed{Answer: B. \frac{7}{21} }$

Good luck on your assignment and enjoy your day!

Solve for x: 2/7(x-2) = 4x

zheka24 [161]

Answer:

2/7(x-2)=4x

(2×x-2×2)/7 = 4x

(2x-4)/7 = 4x

2x-4×(1) = 4x × 7 ( Cross multiply)

2x-4 = 28

2x = 32

2x÷2 = 32÷2

x=16
