It will be b after you do the math
3 quarters and a dime a nickel and 4 pennies
Answer:
14y-13y² is the answer. sorry for dirty handwriting
At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (
)
Let the two numbers be x and y.
Given,
x + y = 23
x = 23 - y
Also given,
y = 2x - 1
y= 2(23 -y) -1
y = 46 - 2y - 1
3y = 45
y = 15
x = 23 - y = 23 - 15 = 8
Hence, the two numbers are 15 and 8.
