Answer:

10

Step-by-step explanation:

So we have the expression:

$|2+3(-4)|$

First, evaluate within the absolute value bars. 3 times -4 is -12. Thus:

$=|2-12|$

Now, subtract:

$=|-10|$

The absolute value of -10 is positive 10. So:

$=10$

And we're done!

Evaluate the expression 3.14(a2 + ab) when a = 4 and b = 3

barxatty [35]

when a=4 and b=3,

3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8

AC=CE and D is the midpoint of CE. If CE = 10x+18 DE = 7x-1 and BC = 9x-3 find AB

Mazyrski [523]

We know the CE = 10x + 18 and DE = 7x - 1 and D is the midpoint of CE

⇒ CE = 2 * DE

⇒ 10x + 18 = 2 * (7x - 1)

⇒ 10x + 18 = 14x - 2

⇒ -4x = -20

⇒ x = 5

Now we also know that BC = 9x - 3 and AC = CE = 10x + 18

⇒ AB = AC - BC

⇒ AB = 10x + 18 - (9x - 3)

⇒ AB = x + 21

Substituting the value of x,

⇒ AB = 5 + 21

⇒ AB = 26

Hence, the value of AB is 26 units.
