A is on the graph. When you plug in 3 in for x you get -4
B is not. When 1 is plugged in you do notnget 4
Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
Perimeter,
Put the value of l from equation (1) to equation (2). So,
Put the value of b in equation (1),
If b = 5 cm
If b = 9 cm
So, the dimensions of the playing card is 9 cm by 5 cm.
D is the correct answer.
When you add fractions, the answer is always rational.
1/5+-2/3= 3/15-10/15 = -7/15
A B and C are all irrational because they are nonterminating and nonrepeating decimals, which cannot be represented as a ratio of two integers. When you add a fraction to an irrational number, the result is still irrational.
If you need 7, 714 solar panels, and 1 box contains 24 panels then you'll need:
7, 714/24 = 321.4167
This answer estimated can be 321. So yuh might need 321 panels.
ANSWER = 321 PANELS
