Answer:

$\frac{1}{2} \: or \: 0.5$

Step-by-step explanation:

$\frac{5}{7} \times \frac{14}{20} = \frac{5 \times 14}{7 \times 20}$

It can be also written as -

$= > \frac{5 \times 14}{20 \times 7} = \frac{5}{20} \times \frac{14}{7} = \frac{1}{4} \times 2 = \frac{1}{2}$

Answer:

17rx2−23rx−71x+75

Step-by-step explanation:

(17x−23)(xr−4)−(3x+17)

=(17x−23)(xr−4)+−1(3x+17)

=(17x−23)(xr−4)+−1(3x)+(−1)(17)

=(17x−23)(xr−4)+−3x+−17

=(17x)(xr)+(17x)(−4)+(−23)(xr)+(−23)(−4)+−3x+−17

=17rx2+−68x+−23rx+92+−3x+−17

=(17rx2)+(−23rx)+(−68x+−3x)+(92+−17)

=17rx2+−23rx+−71x+75

Simplify the expression and SHOW YOUR WORK, please. 10h+6-5h+3

irinina [24]

5h+9 is the right answer. First you had to used group like terms, and it gave us, $10h-5h+6+3$ . Then add similar elements, and it gave us, $10h-5h=5h$ , or $5h+6+3$ . Finally, you had to add by the numbers, and it gave us, $6+3=9$ , or and it gave us the answer is 5h+9 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
