A.) 7^4x = 10
log base 10 (7^4X) = log base 10 (10)
4x log base 10 (7) = 1
4x (0.8451) = 1
3.3804x = 1
x = 0.2958
b.) ln(2) + ln(4x-1) = 5
ln (2 * 4x-1) = 5
ln (8x-2) = 5
log base (3) (8x-2) = 5
e^5 = 8x-2
e^5+2 = 8x
x = 18.8016
The area of a figure is the amount of space the figure occupies
The surface area of the figure is 34.8 square meters
<h3>How to determine the area of the shape</h3>
From the question, we have:
- The dimensions of the congruent squares are 3 m by 3 m
- The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 * Area of square + Area of parallelogram
This gives

Evaluate the products

Evaluate the sum

Hence, the surface area of the figure is 34.8 square meters

Answer:
1.42
Step-by-step explanation:
Well when the dog runs the rabbit runs so to find out if the dog reaches the rabbit and how long it will take, we will use multiples.
DOG: 200 400 600
RABBIT:150 300 450 600
Yes the dog will reach the rabbit and it will take 3 minutes long.
