Consider the enlargement of the pentagon. A small pentagon has a bottom side length of x centimeters and left side length of 7 c

il63 [147K]

Answer:

3.3 cm

Step-by-step explanation:

From the above question, we can draw out a proportion

= Small pentagon = Large pentagon

= x/7 = 7/15

Cross Multiply

x × 15 = 7 × 7

15x = 49

x = 49/15

x = 3.2666666667 cm

Approximately= 3.3 cm

1.6/n = 1.2/20<br> What's the correct answer?

natita [175]

Answer:

n = 26 2/3

Step-by-step explanation:

Step 1: Cross-multiply.

$(1.2) * (n) + 1.6*20$
$1.2n =32$

Step 2: Divide both sides by 1.2

$1.2n/1.2 = 32/1.2$
$n = 26\frac{2}{3}$

Therefore, the answer is n = 26 2/3.

4(5+4)

Step-by-step explanation:

4(5+4) equals 36, and 20 + 16 equals 36 as well, so therefore 20 + 16 is equivalent to 4(5+4)
