300 x 700 = 210,000 square feet

600 x 1400 = 840,000 square feet

840,000 - 210,000 = 630,000 square feet difference

Matthew is paid $8.50 for each acre he mows on his grandparent's estate. He mows 50% of an acre in 3/5 of an hour.
Blizzard [7]

Question

At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.

Answer:

exact answer =$19.83

rounded answer = $20

Step-by-step explanation:

3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%

16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83

so 8.50 + 8.50 + 2.83 =

$19.83

Algebraically determine the zeros of the quadratic function g(x)= x^2+7x+12. Show all work please
Alinara [238K]

Answer:

x = - 4, x = - 3

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

x² + 7x + 12 = 0

To factorise the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)

The factors are + 4 and + 3, since

4 × 3 = 12 and 4 + 3 = 7, hence

(x + 4)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 3 = 0 ⇒ x = - 3

Write a polynomial function in standard form with given zero x=2,-1,-5
LekaFEV [45]

Answer:

Done below!

Step-by-step explanation:

(x - root)

(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

(x^{2} +x-2x-2)(x+5)=(x^{2} -x-2)(x+5)=x^{3}+5x^{2}-x^{2}   -5x-2x-10\\\\=x^{3}+4x^{2} -7x-10
