Answer: See below
Step-by-step explanation:
a) 6(3x+4y-8)
Use the distributive property:
6*3x + 6*4y - 6*8
18x + 24y - 48
<u>So D is the correct answer</u>
b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.
12+4x
= 4(3+x)
<u>So D is the correct answer</u>
c) When you expand both <u>C and D</u> and simplify, you get 16x+36 as solution
d) 14x+2y+10z
Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times
14x+2y+10z
= 2(7x+y+5z)
<u>So D is the correct answer again ;)</u>
I’ll assume the question is asking us to factor the above polynomial:
5x^2 + 10x - 45
Factor out a 5:
5(x^2 + 2x - 9)
This appears to be an irreducible quadratic polynomial, so let’s leave it alone.
5x^2 + 10x - 45 = 5(x^2 + 2x - 9)
Answer:
y = 2x - 8
Step-by-step explanation:
Parallel lines have SIMILAR <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 2 remains the same:
8 = 2[8] + b
↑
16
-8 = b
y = 2x - 8 >> Parallel Equation

Hint: Use decimal concept.
We know that, 1 rupee = 100 paise. We can reframe these questions as follows:
18 rupees 9 paise from 75 rupees 80 paise
18 rupees 9 paise can be represented as 18.09 rupees and 75 rupees 80 paise can be represented as 75.80 rupees. Now, on subtracting we’ll get,
75.80−18.09−−−−−− 57.71
Which means 57 rupees 71 paise
49 rupees 79 paise from 123 rupees 68 paise
49 rupees 79 paise can be represented as 49.79 rupees and 123 rupees 68 paise can be represented as 123.68 rupees. Now, on subtracting we’ll get,
123.68 −49.79−−−−−− 73.89
Which means 73 rupees 89 paise.
Note: We can also perform the subtraction by making all units the same that are paise and then subtract.
