What is (x+6)(x+4)(x-3) expand and simplify

Mathematics
1 answer:
mestny [16]2 years ago

Answer:

x³ + 7x² - 6x - 72

Step-by-step explanation:

Given

(x + 6)(x + 4)(x - 3) ← expand the second and third factor, that is

(x + 4)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) + 4(x - 3) ← distribute both parenthesis

= x² - 3x + 4x - 12 ← collect like terms

= x² + x - 12

Now multiply this by (x + 6) in the same way

(x + 6)(x² + x - 12)

= x(x² + x - 12) + 6(x² + x - 12) ← distribute both parenthesis

= x³ + x² - 12x + 6x² + 6x - 72 ← collect like terms

= x³ + 7x² - 6x - 72

alexdok [17]

Answer:E 83\frac{1}{3}

Step-by-step explanation:

50% of the apartment in a certain building have windows and hardwood floors.

25% of the remaining 50% apartment without window have hardwood floors.

40% of the apartment do not have hardwood floors i.e. 60 % have hardwood floor

Therefore percent of the apartments with windows have hardwood floors is

=\frac{50 percent of total\ apartment }{60\ percent\ of\ apartment}

=83\frac{1}{3}%

Find the values of x and y. PLEASEEE QILL GIVE BRAINLIEST
agasfer [191]

As parallel sides

\\ \rm\longmapsto 2x+90=180

\\ \rm\longmapsto 2x=90

\\ \rm\longmapsto x=90/2=45

Now

\\ \rm\longmapsto 2x+3y+6y+90=360

\\ \rm\longmapsto 9y+180=360

\\ \rm\longmapsto 9y=180

\\ \rm\longmapsto y=20
