Let's solve your equation step-by-step.<span><span>
f<span>(3)</span></span>=<span>−4</span></span>
Step 1: Simplify both sides of the equation.<span><span>
3f</span>=<span>−4</span></span>
Step 2: Divide both sides by 3.<span><span><span>
3f/</span>3</span>=<span><span>−4/</span>3</span></span><span>
f=<span><span>−4/</span>3</span></span>
Answer:<span>f=<span><span>−4/</span><span>3
-Hope this helped
if you legit just meant f(3)
that would be
3f

Answer:
Step-by-step explanation:
Answer: <span>-x2 + 120x = 1,800
</span><span>
She plans on using the side of the barn as one side of her paddock so it has 3 sides. Since the width is shorter, it will be more efficient to have 2 widths (1 lengths and 2 widths). Because J</span><span>ill has 120 feet of fencing to use, you can get this equation:
120ft= 1L +2W
</span>1L= 120-2W
If you insert it into area formula it would be:
area= L*W
area= (120-2W) *W
area= 120W- 2W^2
-2W^2+120W= area
<span>Since x represent the width of the paddock and the area is 1800 the equation become
</span>-2X^2+120X= 1,800
We get 15 feet and 20 inches and since 12 inches = 1 foot
16 feet 8 inches
