Since you know that a square has 4 equal sides then you know the small squares are 4cm on all sides and the big squares are 9cm on all sides.

If 2 and a partial sm sq are next to a 9cm sq then knowing 4*2=8 you can figure out that the other square is split as 1cm and 3cm(1+3=4), 3cm of which is lined up with the width (4cm)of another sm sq which would equal 7cm, these 2 sm sqs line up with the unknown sq whose sides would in turn also be 7cm.

A=l*w, 7*7=49

Answer:Area=49cm^2

Ronch [10]

Answer:

Step-by-step explanation:

Slope intercept form: y =mx +c

5x - 2y = 10

-2y = -5x + 10

$\dfrac{-2y}{-2}=\dfrac{-5x}{-2}+\dfrac{10}{-2}\\\\\\y=\dfrac{5}{2}x-5$

Luiza starts collecting rare coins. In the first month of her collection, she has 25 coins. Each month since then, she has added

almond37 [142]

Answer: 71 coins

Step-by-step explanation:

First and foremost, we should note that:

12 months = 1 year

2 years = 12 × 2 = 24 months

Since she has 25 coins in her first month and adds 2 coins to her monthly collections, this means that she has 23 more months. This can be expressed as:

= 25 + 2x

where, x = number of months

= 25 + 2(23)

= 25 + 46

= 71 coins

She will have 71 coins after 2 years.
