Problem Overview:
The task involves identifying the
two correct equations for each array of flowers. Each array represents a multiplication or addition scenario, and we need to match it with the correct mathematical expressions.
Step-by-Step Solution:
####
Array 1:
-
Image Description: There are
2 rows of flowers, with
4 flowers in each row.
-
Total Flowers: \( 2 \times 4 = 8 \) or \( 4 + 4 = 8 \).
-
Equations to Check:
1. \( 4 + 4 = 8 \)
2. \( 2 + 2 + 2 + 2 = 8 \)
3. \( 4 + 2 = 6 \)
4. \( 2 + 2 = 3 \)
-
Correct Equations:
- \( 4 + 4 = 8 \) (Adding the number of flowers in each row)
- \( 2 + 2 + 2 + 2 = 8 \) (Adding the number of flowers column-wise)
####
Array 2:
-
Image Description: There are
3 rows of flowers, with
5 flowers in each row.
-
Total Flowers: \( 3 \times 5 = 15 \) or \( 5 + 5 + 5 = 15 \).
-
Equations to Check:
1. \( 5 + 5 + 5 = 15 \)
2. \( 2 + 2 + 2 + 2 + 2 = 10 \)
3. \( 5 + 5 = 10 \)
4. \( 4 + 4 + 4 + 4 = 16 \)
-
Correct Equations:
- \( 5 + 5 + 5 = 15 \) (Adding the number of flowers in each row)
- \( 3 \times 5 = 15 \) (Not explicitly listed, but implied by the structure)
####
Array 3:
-
Image Description: There are
3 rows of flowers, with
3 flowers in each row.
-
Total Flowers: \( 3 \times 3 = 9 \) or \( 3 + 3 + 3 = 9 \).
-
Equations to Check:
1. \( 3 + 3 + 3 = 9 \)
2. \( 3 + 3 + 3 + 3 = 12 \)
3. \( 4 + 4 + 4 = 12 \)
4. \( 3 + 4 + 3 + 4 = 14 \)
-
Correct Equations:
- \( 3 + 3 + 3 = 9 \) (Adding the number of flowers in each row)
- \( 3 \times 3 = 9 \) (Not explicitly listed, but implied by the structure)
####
Array 4:
-
Image Description: There are
4 rows of flowers, with
5 flowers in each row.
-
Total Flowers: \( 4 \times 5 = 20 \) or \( 5 + 5 + 5 + 5 = 20 \).
-
Equations to Check:
1. \( 5 + 3 = 8 \)
2. \( 3 + 3 + 3 + 3 + 3 = 15 \)
3. \( 5 + 5 + 5 = 15 \)
4. \( 5 + 5 + 5 + 5 = 20 \)
-
Correct Equations:
- \( 5 + 5 + 5 + 5 = 20 \) (Adding the number of flowers in each row)
- \( 4 \times 5 = 20 \) (Not explicitly listed, but implied by the structure)
Final Answer:
\[
\boxed{
\begin{array}{l}
\text{Array 1: } 4 + 4 = 8, \, 2 + 2 + 2 + 2 = 8 \\
\text{Array 2: } 5 + 5 + 5 = 15 \\
\text{Array 3: } 3 + 3 + 3 = 9 \\
\text{Array 4: } 5 + 5 + 5 + 5 = 20
\end{array}
}
