Answer:
The value of the expression at x=5 is 10
Step-by-step explanation:
The given expression is
Let us simplify this expression.
Distribute -2 over the parentheses, we get
Now, substitute x = 5, we get
On simplifying, we get
The value of the expression at x=5 is 10
The complete question is
"What is the value of this expression when c= -4 and d= 10?
1/4 (c^3+d²)
A.2
B.9
C.21
D.41"
The value of this expression when c = -4 and d = 10 will be option B 9.
<h3>What is a simplification of an expression?</h3>Usually, simplification involves proceeding with the pending operations in the expression.

Answer:
The ordinate of B exceeds the ordinate of A by 7
Step-by-step explanation:
Let
A(x1,y1),B(x2,y2)
where
x1 is the abscissa of A
x2 is the abscissa of B
y1 is the ordinate of A
y2 is the ordinate of B
we know that
so
-----> equation A
----> equation B
substitute equation B in equation A
therefore
The ordinate of B exceeds the ordinate of A by 7
