I'll make you brainliest easyquestion 6th grade multiply and add fractions pleaze answer it asap

C

Step-by-step explanation:

Area (A) = length × width

A = 7 × 9

Change both mixed numbers to improper fractions

7 =

9 =

Hence

×

=

=

= 68

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
