Answer:
f(7)= 23
Step-by-step explanation:
since x equals 7, you will want to switch the variable with the exponent. you will multiply 3 by 7 and you will get 21. after that you should add 2 and get 23. idk if i gave the right equation but i hope this helps!
300. You're multiplying 30 by 10, so you take the 0 off the ten and add it to the 30; it becomes 300
The triangles are said to be similar, so the measures of sides in the larger triangle are proportional to the measures of sides in the smaller triangle. The measures of the two long sides have the ratio 182:65, so we expect the ratio of the shortest sides to be the same:
... ? : 45 = 182 : 65 . . . or . . . ?/45 = 182/65
Multiplying the equation by 45 gives us
... ? = 45·(182/65) = 126
The appropriate choice is ...
... C. 126
