Write an expression for the calculation triple 4 and then add 7 times 7

Answers

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

\frac{1}{4}=\frac{x}{5}\\\\x=\frac{4}{5}\\\\x=0.8

hence, first option 'a'   is correct.

The answer is 3. parallelogram
X = (((3*4)+7)*7)

Where x is the result of the calculation.
(((3(4))+7)(7)) is the answer
