ΔXPS is congruent to ΔDNF
Since they only give you two sides of ΔXPS, then you know that:
XP (4y-3)= DN (57)
XS (17x+3) = DF (54)
4y - 3 = 57
4y = 60
y = 15
17x + 3 = 54
17x = 51
x = 3
So the answers are:
x = 3
y = 15
Answer:
45.6 mph
Step-by-step explanation:
Well,
If Bird A is EXACTLY 5 times as fast as Bird B, then it can reach 228 mph and Bird A can only reach 45.6 mph.
Like this: √32-5√2 ? The answer would be −1.414213562
Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
