Answer:
1/2
Step-by-step explanation:
Both fractions can be expressed using a denominator of 10. The sum can be reduced by removing a common factor of 5 from numerator and denominator.
The product of 5 3/4 X 4 2/9 is equal to 24 5/18
<span>twice the sum of a number and seven is 8
2(x+7)=8</span>
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself.
