1. The length of a rectangular box is 2 units rebuff than its width. If the area of the box is 15 units square. Find the perimeter of the box.   B. 16(Correct Answer)  description These are the formulas for the box. A= L x W P = 2( L + W) We know that the area is 15 15= L x W Also, L= W-2 Now we bathroom handling both formulas (W)(W-2) = 15 W² - 2W= 15 W²- 2W-15= 0 (W-5) (W+3) = 0 W= 5 , W= -3 We can d minuteyl the Length, L = W-2 = 5- 2= 3 L= 3 at last the perimeter: P = 2( 3+ 5) P = 2(8) P= 16 2. Evaluate the pursuit expression if X=-2, Y= 3, Z= -5 2X²-3Y-3Z   D. 14(Correct Answer)  accounting 2(-2)² -3(3) -3(-5) = 2(4) -9 +15 = 8-9 +15= 14 3. Simplify:   C.  (Correct Answer)   rendering You exact to simplify separately exponent, since you are dealing with a square root you need to rewrite the exponents as all the same exponents. a³ = a²a b?= b?b Z³ =Z²Z Now you can grant the exponents by two: ab³Z and the balance bike has to be inside the square root ?(abZ) 4. Multiply: (3X -5)(2X+ 5)    5. act: 3(5X-1)<4(X-6)  account statement 3(5X-1)<4(X-6) 15X-3 < 4X -24 15X-4X < -24 + 3 11X < -21 X< -21/11 6.

Solve for X: 3(X-5)-4X = 6(X-10) -(X+ 5)  Explanation 3X -15 -4X= 6X -60 -X- 5 -X -15= 5X -65 -6X= -65 +15 -6X= -50 X= -50/-6 = 25/3 7. Translate the following blame into an algebraic expression: The fruit of a rate and half dozen is three quantify the same number slight than ex Explanation The result message multiplication: 6 and X is means concern sign = th ree times the same number less than ten 10 ! -3X 8. Simplify: -3(p-5p²) + 3p²-6P  Explanation -3p + 15p²+ 3p²-6p= 18p²-9p   9. Which of the following equations passes by means of point  (-3,-16) 10. ------------------------------------------------- Top of Form 11. Bottom of Form Explanation Substituting the determine in all the equations we get that the result is Y= 2X-10...If you emergency to get a full essay, assign it on our website: OrderEssay.net
