Answer:
x + 11
Step-by-step explanation:
out you're going from -3 to 8 and that is 11 jumps so if x is -3 then it would be x + 11
Answer:
x² + 23x + 49
Step-by-step explanation:
Since the area of a rectangle is: A = l x w, where l = length and w = width, we can find the overall area of the shaded region by multiplying the entire area and subtracting the smaller area of the unshaded square:
(2x + 5)(x + 10) - (x + 1)² or (2x + 5)(x + 10) - (x² + 2x + 1)
Distribute/FOIL:
2x² + 20x + 5x + 50 - x² - 2x -1
Combine like terms:
x² + 23x + 49
Let the age of the son be x, then the age of the father = 6x
x + 6x = 42
7x = 42
x = 42/7 = 6
Therefore the age of the son is 6 while the age of the father is 6(6) = 36.
Answer:
x = 5/(a+3-b)
Step-by-step explanation:
ax+3x = bx+5
ax+3x-bx = 5
Take x as a common.
x(a +3 - b) = 5
x = 5/(a+3-b)
