Answer:

A) 2x³+11x²+8x-16

Step-by-step explanation:

When you multiply s(x) by t(x) you get something like this:

$s(x) \times t(x) = (2 {x}^{2} + 3x - 4) \times (x + 4) \\ = 2 {x}^{3} + 3 {x}^{2} - 4x + 8 {x}^{2} + 12x - 16 \\ = 2 {x}^{3} + 11 {x}^{2} + 8x - 16$

Answer: A) 2x³ + 11x² + 8x - 16

Step-by-step explanation:

s(x) · t(x) = (x + 4)(2x² + 3x - 4)

= x(2x² + 3x - 4) + 4(2x² + 3x - 4)

= 2x³ + 3x² - 4x + 8x² + 12x - 16

= 2x³ + (3x² + 8x²) + (- 4x + 12x) - 16

= 2x³ + 11x² + 8x - 16

what number must be added to 3 and 8 so that the ratio of the first number to the second number is equal to 3 :4

Grace [21]

The answer is 12.
Steps
If that number is x
(3+x)/(8+x)=3/4
"Cross multply"
4(3+x)=3(8+x)
12+4x=24+3x
x=12
To check: add 12 to 3 and 8. 3+12=15 and 8+12=20. 15/20=3/4

Dahasolnce [82]

To find area we multiple length by width

20 times 45 is 900

then multiply that by 2 because there are two floors that are that size

900 times 2 is 1800

the total area for both floors is 1800 square feet
