Answer:
Step-by-step explanation:
Area = length * width
length: x + 3
width: x - 5
A = (x + 3)(x - 5)
Simplify (x + 3)(x - 5) using the FOIL method:
1. First numbers: multiply the first number of each binomial together--x*x = x%5E2
2. Outer numbers: multiply the outer number of each binomial (out of the entire expression, the number farthest to the left (x) and the number farthest to the right (-5))--x*-5 = -5x
3. Inner numbers: multiply the inner number of each binomial--3*x = 3x
4. Last numbers: multiply the last number of each binomial--3*-5 = -15
==> Now, add all of the results together and combine like terms: x%5E2+-+5x+%2B+3x+-+15 = x%5E2+-+2x+-+15
Therefore, A = x%5E2+-+2x+-+15
Solve your equation step-by-step.
x^2+5=41
Subtract 5 from both sides.
x^2+5−5=41−5
x^2=36
Take square root.
x=±√36
x=6
or
x=−6
So your answer suppose to be C and D.
But if you were to put only one answer in the answering box, then just say C)
If you were asking for how many packages you would like if each you would want one pack of crackers, and two packages of cheese. Simple math. The reason why you get that answer and that equation/solution, is by simply make ing the cheese grater then the crackers, but if the cheese is lower then the crackers, you get more cheese packages because then you get two times the cheese and you will have enough cheese for all the crackers. You may have a little bit of cheese left, but who doesn't like it plain? That is the answer.
Answer: 150
Step-by-step explanation:
20 is 1/3 of 60. So you can just multiply 50x3 so the answer becomes 150.
Let the number be y.
so,
50% × y = 7.5
move 50% to the other side
y=7.5÷50%
therefore y=15
