Answer:

-3x^2 * x = -3x^3\\y * y = y^2

(-3x^2y)(5xy^2 + xy)\\

Use F.O.I.L, (First Outer Inner Last) to multiply. Start with -3x^y * 5xy^2

Start with similar terms

-3x^2 * 5x = -15x^3\\y * y^2 = y^3\\Therefore,\\-15x^3y^2

Move onto the xy portion of the problem

-3x^2y(xy)\\

Start with similar terms

-3x^2 * x = -3x^3\\y * y = y^2\\Therefore,\\-3x^3y^2

Combine the two together

-15x^3y^3 - 3x^3y^2\\

The answer is Option A

Paul [167]

Flipping is intended for pinpoint presentation to visible, thick cover between 10 and 25 feet away. I use a heavy-action Vexan. 7'4" H to 7'10" XH rod. Use 40- to 85-pound braided line, such as SpiderWire, for bait casting rods; downsize your line on spinning reels for smaller baits (like finesse baits) or during cold fronts. Let out about 7 feet of line. With your free hand, grasp the line between the reel and the first rod guide and straighten your arm to the side. There should now be about 7 feet of line past the front tip. Raise the rod to make the lure swing back close to your body. Lower the rod tip to make the lure swing forward. Use only your wrist, and roll the butt of the rod to the inside of your arm. As the lure moves past the rod tip, continue raising the rod as you feed line with your free hand. As the lure nears the water, lower the rod tip again and make the bait touch down precisely on target by stopping the bait just before it enters the water. Tighten your drag all the way for increased hookset ratios and when you think there’s a strike, reel down until your rod is in hookset position before setting the hook. One last tip from a pro, use scent when trying to penetrate thick cover — it acts as a lubricant to allow the bait to ease into the cover.
