1 + 4 = 5, in this question, there is 1 "4", and 1 + 4 = 5
2 + 5 = 12, in this question, there are 2 "5", and 2 + 5 + 5 = 12
3 + 6 = 21, in this question, there are 3 "6", and 3 + 6 + 6 + 6 = 21
So for 5 + 8, there are 5 "8", so:
5 + 8 + 8 + 8 + 8 + 8 = 45
45 is your answer
hope this helps
First, find the scale factor.
8.4 / 7 = 1.2
9 / 7.5 = 1.2
7.2 / 6 = 1.2
Since both solids are different sizes, the solids aren't congruent.
The size ratio for all the sides are:
8.4:7
9:7.5
7.2:6
Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.
Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.
Best of Luck!
Hello,
answer f: conjugate
if all coefficients are real and a+ib a zero, its conjgate a-ib is also a zero.
Answer:
Greater than 3
Step-by-step explanation:
Logarithms explain the relationship between exponents.
Think of them as such, except they got their bases and exponents switched.
In this logarithm:
basically says 2 to the power of <em>what</em> gets you to 10.
Now let's experiment: 2^2=4, 2^3=8. 2^4=16.
Wait, we already crossed 10. Now we know that log2(10) must be in between 3 and 4. We don't need to find the exact value, because thats not what the question asked.
It's between 3 and 4, so it has to be greater than 3 but less than 4. Thee is your answer!
Have a nice day! :)
Answer:
C
Step-by-step explanation:
When you are given any number to an exponent, you need to multiply it by itself as many times as the exponent's number. For example, if you got 4^7, you would multiply 4 * 4 * 4 * 4 * 4 * 4 *4 for a total of 7 times. In this case, it is 1/2 * 1/2 * 1/2 because the exponent is 3, meaning you do that 3 times.
