1. Check the sketch of the problem.
2. In right triangle DCE,
tan 50 can be found to be 1.19 using a scientific calculator or other software.
x=1.19*50=59.5 (feet)
3. The height of the building is 59.5+5=64.5 (feet)
Answer: 64.5 (feet)
Answer: x > 12
<u><em>Step 1.</em></u>
Add 5 to both sides.
2x - 9 + 9 > 15 + 9
2x > 24
<em><u>Step 2.</u></em>
Divide both sides by 2.
2x ÷ 2 > 24 ÷ 2
x > 12
Hence, x > 12 is the answer
New problem: 3x3 (2x4 - 3x-5)
First you would solve the first set of multiplication
After multiplying: 9(8-15)
Then you have to multiply 9x8 and 9x15
72- 135 = (Answer is C) -63
Polynomials are classified according to their number of terms. 4x 3<span> +3y + 3x </span>2<span> has three terms, -12zy has 1 term, and 15 - x </span>2<span> has two terms. As already mentioned, a polynomial with 1 term is a </span>monomial<span>. A polynomial with two terms is a </span>binomial<span>, and a polynomial with three terms is a </span>trinomial<span>.</span>
