R+p=28 → p=28-r
2r+28-r=43 → r=15
p=28-15=13
Bruce has 15 Orioles cards and 13 Pirates cards
Mila has 30 Orioles cards and13 Pirates cards
So they have 45 Orioles cards and 26 Pirates cards

What is the value of x?<br><br> _________ *
Flura [38]

Look at the picture.


The angle y° and 71° are Supplementary Angles. Therefore y° + 71° = 180°.


y^o=180^o-71^o=109^o


The sum of measures of these three angles of any triangle is invariably equal to 180°.

Therefore we have the equation:


x^o+109^o+28^o=180^o\\\\x^o+137^o=180^o\ \ \ |-137^o\\\\x^o=43^o

Jake wants to enlarge 12 ft by 14 foot garden if you multiply two Dimensions by to how will the area of the garden be affected​
Tatiana [17]

Answer:

A. It will be multiplied by 4.

Step-by-step explanation:

When all the dimensions of a 2-dimensional figure are multiplied by a number x then the area is multiplied by x^2. Since all numbers are multiplied by 2 then the area will be multiplied by 2^2 or 4.

To prove this:

12*14=168

Now double the dimensions

24*28=672

Notice that 168*4=672

If this helped please consider giving brainliest.
