Sure, let's solve these step-by-step.
11) [tex]\( 1 \times 14 = 1 \times (c +) =\ \square\ +\ \square\ = \square \)[/tex]
- Here it seems like there is some missing information on purpose or it may be a typo.
- [tex]\( 1 \times 14 \)[/tex] equals 14
- So we assume [tex]\( c = 14 - b \)[/tex] (meant to balance out, but need restructuring since c isn't defined properly)
- If we correct, [tex]\( c + b = 14 \)[/tex]
12) [tex]\( 1 \times 25 = 1 \times (+5) = \square\ +\ \square\ = \square \)[/tex]
- [tex]\( 1 \times 25 \)[/tex] equals 25
- Let's assume we want to express this somehow.
- [tex]\( 25 = 20 + 5 \rightarrow \text{missing part: 20}\)[/tex]
- Correctly rewritten: [tex]\( 25 = 20 + 5 \)[/tex]
13) [tex]\( 2 \times 17 = 2 \times (\star) = \square + \square \square = \square \square \)[/tex]
- [tex]\( 2 \times 17 \)[/tex] equals 34
- Assume [tex]\( \star = 17 \)[/tex] (following same construct)
- Correctly reconstructed sum: [tex]\( 34 = 30 + 4 \)[/tex]
14) [tex]\( 3 \times 15 = 3 \times (4) = \square + \square = \square \)[/tex]
- [tex]\( 3 \times 15 \)[/tex] equals 45
- 4 doesn't impact result; correction perhaps:
- [tex]\( 45 = 30 + 15 \)[/tex] where 3(5); typo fixed within.
15) [tex]\( 3 \times 18 = 3 \times (+x) = \quad + \square = \square \)[/tex]
- [tex]\( 3 \times 18 \)[/tex] equals 54
- Assumed [tex]\( x = 18 \)[/tex]
- Balance correct; deficient in [tex]\( + part, 54 = 30+24\)[/tex]
- Fix: [tex]\( 54 = 30 + 24 \)[/tex]
16) [tex]\( 5 \times 13 = 5 \times (3+) = \square + \square = \square \)[/tex]
- [tex]\( 5 \times 13 \)[/tex] equals 65
- Assumed [tex]\( x as 3+\)[/tex]
- A [tex]\( =15+ remaining, 50? Corrected\)[/tex]
- Revised: [tex]\( 65 = 15 + 50\)[/tex]
So we arrive at solutions:
11) Needs further validation per missing data /
( [tex]\( 14= something?\)[/tex] )
12) Fitting 25 equality: [tex]\( 25 = 20 + 5 \)[/tex]
13) [tex]\( 34 = 30 + 4\)[/tex]
14) Corrected [tex]\( 45 = 30 + 15 \)[/tex]
15) [tex]\(54 = 30+24\)[/tex]
16) Correct [tex]\( 65 = 15 + 50\)[/tex]
Revised assumptions\ included clarifying typographical issues logically.
