Answer:
1. not equal, 2. equal, 3. 18
Step-by-step explanation:
7/5 =1.4
15/10=1.5
1.4 does not equal 1.5
6/8=.75
15/20=.75
.75 equals .75
1.2*3/2=1.8
Answer:
The three consecutive odd integers are: -11, -13 and -15.
Step-by-step explanation:
Let the smallest number be represented by x. then the three consecutive odd integers are: x, (x + 2) and (x = 4).
The sum of the smallest number and twice the larges number = x + 2(x + 4)
Fifteen more than four times the middle number = 4(x + 2) + 15
So that;
x + 2(x + 4) = 4(x + 2) + 15
x + 2x + 8 = 4x + 8 + 15
3x + 8 = 4x + 23
3x - 4x = 23 - 8
-1x = 15
⇒ x = -15
(x + 2) = (-15 + 2) = -13
(x + 4) = (-15 + 4) = -11
The three consecutive odd integers are: -11, -13 and -15.
Answer:
25 K³ - 35k²+ 50 K - 40
===========================================
Step-by-step explanation:
Given that :
(-5k + 5)(-5k² + 2k - 8)
= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)
= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40
= 25 K³ - 35k²+ 50 K - 40
<u>So, the product = 25 K³ - 35k²+ 50 K - 40</u>
