Answer:

Step-by-step explanation:

For Mr Rowley,

Ratio of Number of home works to the number of exit tickets = $\frac{12}{14}$

= $\frac{6}{7}$

= 6:7

For Ms Rivera,

Ratio of Number of home works to the number of exit tickets = $\frac{36}{42}$

= $\frac{6}{7}$

= 6:7

Since, both the ratios are same, fractions will be proportional.

$\frac{12}{14}=\frac{36}{42}$

. Multiply (3x+2)(4x-7)

aleksklad [387]

Answer:

12 $x^{2}$ + 29x - 14

Step-by-step explanation:

(3x+2)(4x-7)

Multiply out 3x first then 2

(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)

12 $x^{2}$ - (- 21x) + 8x + ( -14)

12 $x^{2}$ + 21x + 8x - 14 Combine like terms

12 $x^{2}$ + 29x - 14

The question is "the polynomial is even & positive, does it have 3 or 4 zeros?

sergejj [24]

Even function is symmetrical about the y axis
not sure what it means if the polynomial is positive

the zeroes are how many times it hits the x axis
it hits 4 times so 4 zeros
