Answer:
Step-by-step explanation:
First, expand out the brackets
2 x 1.6a = 3.2a
2 x 0.7 = 1.4
Therefore 3.2a - 1.4 = 8.2
Now solve to find a
3.2a - 1.4 = 8.2
3.2a = 9.6
a = 3

1 can be written as log 10
so,
log 10 - 3 log 5x = log 10 - log (5x)^3
= log 10/(5x^3)
Answer: the first answer choice
Step-by-step explanation: it’s nonlinear because it has a changing slope, and the graph crosses the y axis at -3
A = 4(187*230/2) + 230²
A = 4*21505 + 230²
A = 86 020 + 52 900
A = 138 920 m²
Hope this helps !
Photon
Root both sides of the equation
x+3= plus or minus root 7
Subtract 3 from both sides.
