Step-by-step explanation:
=( n-2)180
= ( 4 - 2 )180
= 360
So, 144 + 90 + m<2 +m<1 = 360
144 + 90 + 85 + m<1 = 360
319 + m<1 = 360
m<1 = 360 - 319
m<1 = 41
their is an unknown angle so let's call it x
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106

Answer:
(1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)
Step-by-step explanation:
2.25 = 9/4
putting decimals into fractions will make this easier
9/4 = 3/2 * 3/2
a²-b² = (a+b)(a-b)
1 - 2.25x^8 = 1²-(3/2x^4)² = (1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)
Y = 4x + 2
y = 4×10 + 2
y = 42
the 10th term is 42
