Well, the standard equation is in the form:
ax + bx = c (constant).
Thus, x and b must be isolated together on one side with the constant on the other. The equation which satisfies this is:
A. -2x + y = 5
X^2 - 25 is a difference of squares which has a special factorization.
In general, a^2 - b^2 = (a + b)(a - b)
x^2 - 25 = 0
(x + 5)(x - 5) = 0
x + 5 = 0 or x - 5 = 0
x = -5 or x = 5
Answer:
3x > 37
x > 12.333
Thus, 13 and 15 satisfy

$24 if it is at the beginning of the day and he is left with $11, and if he spent $13, then 11+13=24
Answer:
363
Step-by-step explanation:
Formula for area of a circle
A = πr^2
Where r = radius
The circle has a given radius of 11
To find the area of the circle we simply substitute r in the formula with the value of the radius (11)
( Also note that the question says to use 3 for π )
A = πr^2
π = 3
r = 11
Substitute values in formula
A = (3)(11)^2
11^2 = 121
A = 121(3)
121(3) = 363
A = 363
