Answer:
D) Square root of 48
Step-by-step explanation:
We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64
a² would have to equal 48. a=√48.
Answer:
(z-6)(z+3)
Step-by-step explanation:
Answer: 40.6
Step-by-step explanation:
When finding perimeter, you have to add all sides. 16 plus 16 equals 32. 4.3 plus 4.3 equals 8.6. 8.6 plus 32 equals 40.6

Answer is 0</h3>
===========================================================
Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log
Answer:
7.2 and 4.8hrs
Step-by-step explanation:
Given the ratio it took them to finish work as 3:2
Total ratio = 3+2 = 5
For the larger ratio;
3/5 *12
= 36/5
= 7.2hrs
For the shorter ratio;
2/5 * 12
= 24/5
= 4.8hrs
Hence the first worker worked for 7.2hrs while the second was 4.8hrs
