The area of a square can be found by knowing the length of one side. Once you know the length of one side, you plug it into this formula:
Area of a square = side × side = side²
The area of a rectangle can be found by knowing the length and width of the rectangle. Once you know that, you plug it into this formula:
Area of a rectangle = length × width
Answer:
The answer is 31
Step-by-step explanation:
Answer:
Step-by-step explanation:
Step1: isolate the square root on the left hand side.
Original equation :x+1=√-6x-6
Isolate :x+1=√-6x-6.
Step2: raise both sides to the second power.
(x+1)^2=(√-6x-6)^2
(x+1)(x+1)=-6x-6
Step3: after squaring, solve the quadratic equation.
x^2+2x-1=-6x-6
x^2+8x+7=0
x^2+7x+x+7=0
x(x+7)+1(x+7)=0
(x+1)(x+7)=0
x=-1,-7
Step4:check that the first solution correct.
Input x=-1 into the original equation
x+1=√-6x-6
-1+1=√+6-6
0=0
Step5:check that the second equation is correct.
Input x=-7 into the original equation
x+1=√-6x-6
-7+1=√42-6
-6=√36
-6#6
Therefore one solution is found.
x=-1
Answer: If you mean 5% of $14.98, it is $0.75 75 cents
If you mean 14.98 represents a 5% commission on what sale amount
The sale amount was $299.60
Step-by-step explanation:
Change the percent to a decimal and multiply by the sale amount.
0.05 × 14.98 = .749 Round to .75
If 14.98 is the 5% commission, divide 14.98/.05= 299.60
Answer:
-18, -26
Step-by-step explanation:
The differences are decreasing by 1 each time, so the next differences will be -7 and -8.
-11 -7 = -18
-18 -8 = -26
