Answer:
A = 49 in^2
Step-by-step explanation:
The perimeter of a square is found by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want to find the area
A = s^2 where s is the side length
A = 7^2
A = 7^2
A = 49 in^2
Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.

Hello
Answer:
The correct answer is B
Step-by-step explanation:
You just use the Distribuatd property to solve
You multiply 10 to all the varibles inside the parthense
Becasued y is equal to 7 you would do 10x7=70
then 10x8=80
and 70+80=150
and the answer says the primeter is 150 when y=7

Answer:
C ) 40w + 300 > 7--
Step-by-step explanation:
Since he starts off with 300 cards, the equation must have +300 units. As he purchases 40 each week, the rate of change is 40w. Since his goal is over 700, look for >700.
Therefore 40w + 300 > 700
