Answer:
x= -4, 4
Step-by-step explanation:
(x+3)(x-3)=7
FOIL
first x*x
outer x*-3 = -3x
inner 3*x = 3x
last 3*-3 = -9
add them together
x^2 -3x+3x -9 = x^2 -9
x^2-9 =7
add 9 to each side
x^2 -9+9 = 7+9
x^2 = 16
take the square root of each side
sqrt(x^2) = sqrt(16)
x = +- 4
The answer is totally 1 since all of the integers are divisible by one. In addition to one, 3 is also divisible since 12/3=4 and 63/3=21
Figure 1 3 rectangles
Figure 2 2 rectangles, 1 triangle
Figure 3 1 rectangle 1 semicircle
To find the fraction with the greatest value we have to find a common denominator.
1/8 = 3/24
5/12 = 10/24
9/12 = 18/24
Now we can make a direct comparison
The greatest value is 9/12
Answer:
400
Step-by-step explanation:
(15/100)*n=60
Multiplying both sides by 100
15n=60*100
15n=6000
n=6000/15(dividing both sides by 15)
n=400
