Answer:
it is the 2nd option
Step-by-step explanation:
Hey there! I'm happy to help!
If we have g(-3) we plug -3 into our function as x.
-3-2(-3)²
-3-2(9)
-3-18
-21
g(-3) is -21, so now we just add 13.
-21+13=-8
The answer is -8.
Have a wonderful day! :D
Answer:
Length = 502 ft
Width = 212 ft
Step-by-step explanation:
Recall the formula for the perimeter of a rectangle of length "L" and width "W":
Perimeter = 2 L + 2 W = 1428 ft
Now, since the length is 78 ft more than twice the width, then we can write this in mathematical form as:
L = 2 W +78
so, 2 W = L -7 8
and now replace "2 W" with it equivalent "L - 78" in the first perimeter equation and solve for "L":
2 L + L - 78 = 1428
3 L = 1428 + 78
3 L = 1506
L = 1506/3
L = 502 ft
Then the width W can be obtained via:
2 W = L - 78
2 w = 502 -78
2 W = 424
w = 212 ft
