Answer:
45
Step-by-step explanation:
We have the equation 2x² + 6x + 9 and are asked to find the value when x =3.
To solve this, all we need to do is substitute all variables with "x" to 3. Then do the properties :
2x² + 6x + 9
2(3)² + 6(3) + 9
Do exponents first :
2(9) + 6(3) + 9
Now multiply the numbers with parenthesis next to them :
18 + 18 + 9
Add to get the answer :
45
Answer:
see below
Step-by-step explanation:
This is a geomtric sequence
an = a1 r^(n-1)
a1 =1 and r=2
an = 2 ^(n-1)
A=a1 =1
B =a2 = 2^(2-1) =2
C =a3 = 2^(3-1) = 2^2 =4
D = a4 = 2^(4-1) = 2^3 = 8
E = a5 = 2^(5-1) = 2^4 = 16
F = a6 = 2^(6-1) = 2^5 = 32
G = a7 = 2^(7-1) = 2^6 = 64
H = a8 = 2^(8-1) = 2^7 = 128
(3x+4)(x+6) is the answer
By pythagorean theorem
a^2+b^2=c^2
We can find that PL is 12.65
and then by altitude theorem
MA*LA=PA^2
we can find the value of MA
12MA=16
MA=1.33
then by the pythagorean theorem
we can use to find PM
MA^2+PA^2=PM^2
so PM=4.22
then to find the are you multiply length by width
PM*PL
12.65*4.22
So the area is 53.38
