Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle

The answer to this question is b
Hello there!
To find the zeros or the roots of a function, you just need to set the function equal to 0 then solve for x.
f(x) = (x + 4)² - 9
Set function equal to 0
(x + 4)² - 9 = 0
x² + 8x + 7 = 0
Now we can factor the left side
(x + 1)(x + 7) = 0
Then set factors equal to 0
x + 1 = 0 or x + 7 = 0
x = 0 - 1 or x = 0 - 7
x = -1 or x = -7
Thus,
The zeroes of the function are -1 and -7
