Answer:
x = 1.24
Step-by-step explanation:
In order to get that x down from its current position of exponential, you need to take either the log or the natural log of both sides. The power rule tells us that we can then pull the exponent down in front. So let's take the natural log of both sides:
We can bring the x down in front to give us:
ln(83) = x ln(35)
The right side of this is "stuck" together by multiplication, so we can undo that multilication by division of the ln(35). That leaves us with just x on the right:
Do this on your calculator and find that x = 1.24
i believe the answer would be x > 1?
Answer:
y=-3
Step-by-step explanation:
first distribute then solve for y
5y+2=-13
-2 on both sides
5y=-15
divide by five on each side
y=-3

The area of the picture is , (20-2x)(12-2x)=84 i.e, Option A
Step-by-step explanation:
Given,
The length of the outer rectangle = 20 cm
The width of the outer rectangle = 12 cm
The area enclosed by the frame = 84 sq cm
Formula
The area of a rectangle = Length × Width sq m
As per the figure,
The length of the picture = 20-2x [ the frame is x cm wide so, we subtract 2x for both side]
The width of the picture = 12-2x
So, the area of the picture is = (20-2x)(12-2x)
Hence,
(20-2x)(12-2x)=84
