Answer:
Can’t rlly see 1-4
Step-by-step explanation:
5:a=12,b=5
a^2+b^2=c^2
144+25=169
c=13
6: a=8, c=10
64+b=100
b=6
7: a=15,c=17
b=8
8:b=40,c=50
a=30
9:b=2,c=4
a=2 root 3
BE = 6cm
BD = 12 cm
For a square, the diagonal are equal
so :::
AC = BD = 12 cm
Done :)
Answer:
b(10) = 76
Step-by-step explanation:
To find b(10) substitute n = 10 into the formula
b(10) = - 5 + 9(10 - 1) = - 5 + 9(9) = - 5 + 81 = 76
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-
