Analyzing a Factored Polynomial
David found and factored out the GCF of the polynomial Which statements are true about David's work? Check
8064 - 32b2c3 + 48b4c. His work is below.
all that apply
1. GFC of 80, 32, and 48:16
The GCF of the coefficients is correct.
The GCF of the variable b should be b4 instead of
2 GCF of 64. 62and 64b2
b2
3 GCF of c3 and cc
The variable c is not common to all terms, so a
power of c should not have been factored out.
4 GCF of the polynomial: 16b²c
The expression in step 5 is equivalent to the given
5. Rewrite as a product of the GCF:
polynomial
16b²c(562) - 16b?c(202) + 16b2c(362)
In step 6, David applied the distributive property
Factor out GCF: 16b²c(552 - 202 + 3b?)

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
