Answer:
x > 3
Step-by-step explanation:
Given 2 sides of a triangle then the third side x will be
difference of sides < x < sum of sides , that is
15 - 12 < x < 15 + 12, so
3 < x < 27
Thus x > 3
Find the area of all the sides and add together
area of base: = l x w = 5 x 5 = 25
Area of triangle: bh/2 = 5 x 6/2 = 15, but you have 4 of them so you multiply by 4 and get 60
60 + 25 = 85
Answer:
The answer is 2
Step-by-step explanation:
If we use the formula for volume LWH=V. We also take in the fact that a cube has the same measure on every side. and we input 2 for L , W , and H
Which is 2*2*2=8
Answer:
> Using the remainder theorem, set x + 4 to be equal to 0, i.e.
Step-by-step explanation:
> Using the remainder theorem, set x + 4 to be equal to 0, i.e.
x + 4 = 0
x = - 4
=> Substitute - 4 for x in 3x² - x - 2, i.e.
3(- 4)² - (- 4) - 2
= 3 * 16 + 4 - 2
= 48 + 4 - 2
= 52 - 2
= 50 ...
-4|----3----(-1)----(-2)
-------------(-12)------52
________________
------3------(-13)----50
This is wrong.
It's supposed to be -4/15.
But try -4/5.
