Answer:
x = 28
Step-by-step explanation:
12/x = 3/7
Using cross products
3x = 12*7
3x = 84
Divide by 3
x = 28
Answer:
46m + 2mn
Step-by-step explanation:
Before we combine these like terms, let us simplify the exponent:
5m² = 5 × 5
5 × 5
= 25m
= 12m + 25m + 9m + 2mn
Now we can combine them. Only the bolded part should be added because the last value contains 'n" after the "m".
12m + 25m + 9m + 2mn
Add:
12m + 25m + 9m
= 37m + 9m
= 46m
46m + 2mn is our answer.
The radius would be about 161.92
