Answer:
b,c,d
Step-by-step explanation:
a ≤ 10 would have a closed circle at 10
b x+10 <15 x < 10 correct open circle line going to left
c x < 10 correct open circle line going to left
d 0 > x-10 10 > x x < 10 correct open circle line going to left
e 2 > x-11 13 > x would have open circle at 13
Answer:
-12x+18x²
Step-by-step explanation:
Given: 
Distributive property of multiplication under which a number is multiplied by the sum of two number, the first number can be distributed to both of those number.
∴ 
solving it by using distributive property
= 
= 
Opening parenthesis
= 
Hence, -12x+18
is the result after using distributive property.
Remark
Interesting way to teach this problem. I'll see if I can make a table that answers the question as it is presented.
Now all you need do is collect the nine terms from the table and put the like ones together if there are any.
Answer:
36
Step-by-step explanation:
Given
x² + 12x
To make the polynomial a perfect square
add ( half the coefficient of the x- term)²
= x² + 12x + 6²
= x² + 12x + 36
= (x + 6)² ← a perfect square
Answer:
u = 12
Step-by-step explanation:
The equation is showing 5(u) = 60
<u>Begin: 5(u)= 60</u>
2. Divide the 5 from both sides to get the u-value alone.
a) 5u/5 = u b) 60/5 = 12
<u>Now: u = 12</u>
