Write an equivalent expression for n times a using only addition

1 answer:

8 0

Whenever you multiply something, you just add it to itself that many times.

ex) 7 × 4 = 7 + 7 + 7 + 7.

Thus n × a = n + n + n + n....a times.

Answer:

d = $2\sqrt{29}$

Step-by-step explanation:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(0-4)^2+(0-10)^2}\\d= \sqrt{(-4)^2+(-10)^2}\\d= \sqrt{16+100}\\d= \sqrt{116}\\d=2 \sqrt{29}$

Answer:

x= - 8

Step-by-step explanation:

multiply both sides by 4 to get rid of the fractions. you should then get:

2x-4x=x+24

then get all the x terms to one side by subtracting by x on each side:

2x-4x-x=24

then simplify:

-3x=24

divide by -3 on each side:

x= - 8
