Answer:

see explanation

Step-by-step explanation:

A difference of two squares is factored as

a² - b² = (a - b)(a + b)

(g)

1 - 81y²

= 1² - (9y)²

= (1 - 9y)(1 + 9y)

(j)

64x² - 25y²

= (8x)² - (5y)²

= (8x - 5y)(8x + 5y)

The lifespan of a guinea pig is 6 years less than that of a giraffe. The lifespan of a tiger is 4 times that of the guinea pig.

faust18 [17]

Guinea pig (p) = 4 years old
Giraffe (g) = 10 years old
Tiger (t) = 16 years old

P = g-6
T = 4p

30 = g+g-6+(4(g-6))
30 = 2g-6+4g-24
30 = 6g-30
+30 +30
60 = 6g
6 6
10 = g

P = 10-6
P = 4

T = 4(4)
T = 16

Find the sum of polynomials (30 points!!)

hammer [34]

Answer:

2nd option

Step-by-step explanation:

Express the sum of the 2 polynomials by removing the parenthesis , so

5 $x^{5}$ - 2x³ + x + 4 $x^{5}$ - 3 $x^{4}$ + 2x³ - 5x ← collect like terms

= 9 $x^{5}$ - 3 $x^{4}$ - 4x
