Answer:

12 $x^{5}$ + x³ + 6x² - 35x - 10

Step-by-step explanation:

(3x² - 5)(4x³ + 7x + 2)

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

3x²(4x³ + 7x + 2) - 5(4x³ + 7x + 2) ← distribute parenthesis

= 12 $x^{5}$ + 21x³ + 6x² - 20x³ - 35x - 10 ← collect like terms

= 12 $x^{5}$ + x³ + 6x² - 35x - 10

Hey ASAPPP PLS 80 points

Klio2033 [76]

Answer:

using pythagoras theorem

a^2+b^2=c^2

8^2+x^2=(x+2)^2

64+x^2=x^2+2*x*2+2^2

64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)

64=4x+4

64-4=4x

60/4=x

What value of a is a solution to this equation?<br> 1=3+a<br> 4

Romashka-Z-Leto [24]

Answer:

1=a4+3

Step 1: Subtract a^4+3 from both sides.

1−(a4+3)=a4+3−(a4+3)

−a4−2=0

Step 2: Add 2 to both sides.

−a4−2+2=0+2

−a4=2

Step 3: Divide both sides by -1.

−a4

−1

a4=−2

Step 4: Take root.

a=±(−2)(
