Simplify expression:
Step
1
1
1
: Simplify the given expression
9
(
5
z
)
9(5z)
9
(
5
z
)
.
\newline
Calculation:
9
×
5
z
=
45
z
9 \times 5z = 45z
9
×
5
z
=
45
z
.
Compare with choices:
Step
2
2
2
: Compare the simplified expression with each choice.
\newline
(A)
z
(
9
×
5
)
z(9 \times 5)
z
(
9
×
5
)
simplifies to
z
×
45
=
45
z
z \times 45 = 45z
z
×
45
=
45
z
.
Check choice (B):
Step

3
3
: Check choice (B)
9
+

z
9 + 5z
9
+
5
z
.
\newline
Calculation: This expression cannot be simplified to match

.
Check choice (C):
Step
4

4
: Check choice (C)
z

\newline
Calculation: This expression cannot be simplified to match
45
z
45z
45

.
Check choice (D):
Step
5

: Check choice (D) z + 5)9\. Calculation: Distribute \$9 to get
9
z

45
9z + 45
9
z

45
, which does not simplify to
45
