Hi there! :D

Answer:

2(2a+5)

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, rewrite the problem down 10, and then 4.

10=5*2 or 2*5

4=2*2

2*2a+2*5

Finally you had to factor out by the common term of 2.

2(2a+5)

Answer for 5 stars answer and a heart with a comment. Please hurry!

klio [65]

Answer:

Length of the person = 1.9 m

Step-by-step explanation:

Actual length of the lorry = 9.5 m

Length of the lorry as per scale = 10 cm

Scale factor used to get the actual length of the lorry = $\frac{\text{Actual length}}{\text{Length on scale}}$

= $\frac{9.5}{10}$

= 0.95 : 1

Let the actual length of the person = x meters

Length of the person as per scale = 2 cm

Scale factor used to get the length of person is same.

Therefore, relation between the actual length of the person and scale length will be,

$\frac{x}{2}= \frac{0.95}{1}$

x = 2 × 0.95

x = 1.9 meters
