Answer:
Angle BDA is 90°
(2x + 3) + 55 = 90
2x + 3 + 55 = 90
2x + 58 = 90
2x = 90 - 58
2x = 32
x = 32/2
<u>x = 16</u>
Hence,
x=16
x=16Angle BDA is 90°.
time taken is 32 days,!!!!
85% will be correct i feel like
14
Step-by-step explanation:
f(x)=3x²+1
f(2) = 3 x 2² + 1 = 13
g(x) =1-x
g(2) = 1 - 2 = -1
(f-g)(2) f(2) - g(2) = 13 - (-1) = 14
-2/3
I'm not sure but I think the answer is 2187 X^ (14) Y^ ( 42)
(3x^2y^6)^7
3^(7) x (X^)^(7) x ( Y ^(6)^(7)
= 2187 X^ 14)Y^( 42)
