Answer:

Step-by-step explanation:

It is given that A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building, then let AC=14 foot and ∠C=45°and AB be the length of the building.

Thus, using the trigonometry, we have

\frac{AB}{AC}=sin45^{\circ}

Substituting the given values, we get

⇒\frac{AB}{14}=\frac{1}{\sqrt{2}}

⇒AB=14{\times}\frac{1}{\sqrt{2}}

⇒AB=14{\times}\frac{\sqrt{2}}{2}

⇒AB=7\sqrt{2} foot

Thus, the length of the building will be 7\sqrt{2} foot.

c) Combine 2+3 to get 5. 100-(5x5) equals 100-25. 100-25 is 75. The answer is 75.

d) Combine 2+3 to get 5. Combine 1+4 to get 5, which is 25. The answer is 5.

g) Combine 4+6 to get 10. Combine 70+-6 to get 64. Take the root of 64, leaving you with 10-8. Combine 10 + -8 to get 2. The answer is 2.

h) Combine 5+4 to get 9. Take the root of 36, leaving you with 18 + 6.  Combine 18 + 6 to get 24. The answer is 24.


5. [15 + 22 + 53] divided by [12 + 18] = [90] divided by [30] = 3 ribbons each.

6. (4 x 12) + (6 x 8) = 96 total.

Simply the expression given below (3x^3+4x^2+4x-12)+(-5x^3+9x^2-9x+20)
Svet_ta [14]

Answer:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)
