Answer:
Step-by-step explanation:
Given
Attached number lines
Required
Express as: 
The two points on the number line represent x and c (in no particular) respectively.
Solving (a):
Let:
So:
Solve the expression in the absolute bracket
Remove absolute bracket
So: the expression is;
Solving (b):
Let:
So:
Solve the expression in the absolute bracket
Remove absolute bracket
So: the expression is;
Answer:
-q^2 -q + 72
Step-by-step explanation:
(9+ q)(8-q)
=9(8-q)+ q(8-q)
=72 - 9q +8q -q^2
= -q^2 -q + 72
Compare the enumerators because they have the same denominator. 2 is large than 1 so 2/3 is larger than 1/3
Hope this helps!
Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100
