The number that would have to be added to complete the square is 81/4.

<h3>What is a Quadratic Equation ?</h3>

Quadratic equations are polynomials of degree 2 , It is represwented by ax² + bx +c = 0.

The quadratic equation given is

x² -9x +2 = 0

x² -9x + (81/ 4) - (81/4) + 2 = 0

x² -9x + (9/2)² - (81/4) +2 = 0

(x - 9/2)²  - (73/4) = 0

Therefore , 81/4 will be added to complete the square to solve the quadratic equation.

In triangle OPQ, p = 38 cm, q = 29 cm and Angle O=39º. Find the length of o, to the nearest
Lisa [10]

Answer:

The length of o is 24 centimeters

Step-by-step explanation:

In Δ OPQ

∵ Side p is opposite to ∠P

∵ Side q is opposite to ∠Q

∵ Side o is opposite to ∠O

→ To find side o we must use the cosine rule

∴ o = \sqrt{p^{2}+q^{2}-2(p)(q).cos(O)  }

∵ p = 38 cm

∵ q = 29 cm

∵ m∠O = 39°

→ Substitute them in the rule to find o

∴ o = \sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}

∴ o = 23.92008154

→ Round it to the nearest centimeter (whole number)

∴ o = 24 centimeters

∴ The length of o is 24 centimeters

Mr. Arnold needs to paint 1,600 square feet of his house. Each gallon of paint will cover 250 square feet. So you would divide 1600 by 250 to figure out how many cans he needs. the answer is 6.4. Then it says that he had one left over from the last time he painted his house. So he only needs 5.4 gallons now. The end question is whether or not Mr. Arnold needs more than 5 gallons and the answer is yes. Because he needs 5.4 gallons. .4 gallons more than 5.
