I’ll assume the question is asking us to factor the above polynomial:
5x^2 + 10x - 45

Factor out a 5:
5(x^2 + 2x - 9)

This appears to be an irreducible quadratic polynomial, so let’s leave it alone.
5x^2 + 10x - 45 = 5(x^2 + 2x - 9)

Help Please

klasskru [66]

Correct answer is A.

$(x^2+4x-3)(2x^2+x+6)
\\=x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)
\\=2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18
\\=2x^4+x^3+8x^3+6x^2+4x^2-6x^2+24x-3x-18
\\=2x^4+9x^3+4x^2+21x-18$

One end of a ladder 32 feet long is placed 10 feet from the outer wall of a building that stands on the ground level. How far up

ladessa [460]

Answer:

30 ft

Step-by-step explanation:

This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle. Pythagorean's Theorem will help us find this length.

$32^2-10^2=y^2$ so

1024 - 100 = y^2 and

y = 30.4 so 30 feet
