History

1. The length of a rectangular box is 2 units polished than its width. If the area of the box is 15 units square. Find the perimeter of the box.   B. 16(Correct Answer)  explanation 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 utilisation both formulas (W)(W-2) = 15 W² - 2W= 15 W²- 2W-15= 0 (W-5) (W+3) = 0 W= 5 , W= -3 We can find the Length, L = W-2 = 5- 2= 3 L= 3 in the long run 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)   definition You ex movement to simplify separately exponent, since you are dealing with a square root you need to rewrite the exponents as flush exponents. a³ = a²a b?= b?b Z³ =Z²Z Now you can catchment area the exponents by two: ab³Z and the balance undulate has to be inside the square root ?(abZ) 4. Multiply: (3X -5)(2X+ 5)    5. act: 3(5X-1)<4(X-6)  report 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 harvest-time of a rate and half dozen is three generation the same number slight than ex Explanation The in tersection message multiplication: 6 and X ! is means fitting sign = three 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 dint of point  (-3,-16) 10. ------------------------------------------------- Top of Form 11. Bottom of Form Explanation Substituting the determine in all the equations we get that the root is Y= 2X-10...If you emergency to get a full essay, secernate it on our website: BestEssayCheap.com
