Y=(x+3)(x-4)(x+1)^2 sulutions? Multiplicity?
Eddi Din [679]

Answer:

Y = (x + 3)(x - 4)(x + 1)^2

Y = (x^2 - x - 12)(x^2 + 2x + 1)

Y = x^4 + 2x^3 + x^2 - x^3 - 2x^2 - x - 12x^2 - 24x - 12

Y = x^4 + x^3 - 13x^2 - 25x - 12

How many solutions are there to the equation below 15x+11=8x
Svetradugi [14.3K]

Answer:

There is one solution

Giselle works as a carpenter and as a blacksmith. She earns \$20$20dollar sign, 20 per hour as a carpenter and \$25$25dollar sig
Pani-rosa [81]

She earns 20 dollars as a carpenter and 25 dollars as a blacksmith

b+c=30 hours since she works 30 hours a week

25b+20c=690 since she earns 690 dollar totally and earns 25 dollars an hour as a blacksmith and 20 dollars an hour as a carpenter

lets multiply b+c=30 by -20

-20b-20c=-600

if we substract that from

25b+20c=690

5b=90

b=18 she worked as a blacksmith for 18 hours

Please help! need the answer
san4es73 [151]

Answer:

Each base angle is 81°

Step-by-step explanation:

A pennant is in the shape of an isosceles triangle and the vertex angle is 18°.

An iscosceles triangle has two equal sides and two equal angles.

So assuming the base angles measure b° each;

b° + b° + 18° = 180° (angles in a triangle add up to 180°)

2b° = 180° - 18° = 162°

b = 162° ÷ 2 = 81°

So each base angle is 81°
