Find the missing factor 4x^2+19x-5=(x+5)( ) NEED HELP PLEASE

Mathematics
1 answer:
S_A_V [24]3 years ago
4 0

Answer:

4x^2+19x-5=(x+5)(4x -1)

Step-by-step explanation:

The given expression is 4x^2 + 19x - 5

The leading coefficient is 4 and last term is -5

Multiply them, we get -20

Now find the factors of -20 such that when you add the factors we have to get 19.

-1*20 = -20

20+ (-1) = 19

The right factors are -5 and 9.

4x^2 + 19x - 5 =4x^2 + 20x -1x - 5

= 4x(x + 5) -1(x + 5)

= (x + 5)(4x -1)

The missing factor is (4x -1)

Thank you.

balu736 [363]

Answer:

French test

Step-by-step explanation:

We first calculate the scores as percentages:

#Spanish test:

=\frac{score}{total}\times 100\%\\\\\\=\frac{27}{32}\times 100\%\\\\=84.38\%

#For the French test, her percentage is:

=\frac{score}{total}\times 100\%\\\\=\frac{19}{21}\times 100\%\\\\=90.48\%

Since, 90.48$>84.38%, Claire did better in the French test.

HELP PLEASE
Jet001 [13]

Answer:

c $11,751

Step-by-step explanation:

The function that models Alicia's car is

f(x) = 21000(0.93)^{x}

where x represents the number of years since she purchased the car.

We want to find the value of Alicia's car after 8 years.

We substitute x=8 into the formula to get:

f(8) = 21000(0.93)^{8}

f(8) = 21000(0.5596)

f(8) = 11751.218

We round to the nearest dollar to get:

f(8) =11751

The correct answer is C.
