Answer:
Hello! Mizuki here to help!
The correct answer for problem 9 is B.
The correct answer for problem 10 is also B.
Step-by-step explanation:
<em>Sorry if the work I did is confusing, if you don't get what I did, just comment below and I'll try my best to answer your question!</em>
problem 9 work:
3 x 4 + 5 x 8 + 4 x 8 + 3 x 8 =
12 + 40 + 32 + 24 =
108
problem 10 work:
17 x 24 + 8 x 15 + 15 x 24 + 8 x 24 =
408 + 120 + 360 + 192 =
1080
Answer:
x = -7
Step-by-step explanation:
This is an exponential equation.
We need to take log(or ln) of both sides and use logarithm property to solve this.
So, let's take ln of both sides, so we have:
Now, we will use this property shown below to further simplify:
So, we now have:
The value of x is -7
The best choice would probably be the third option from the top. Since by using the distance formula you can solve for the length or distance of each of the sides of the triangle, and check to see if it is equal. As would be in an equilateral triangle.
Slope wouldn’t be best for the last leg or bottom leg as there is no change in y and x.
Answer:
D. x = 5.4, y = 6.67
Step-by-step explanation:
The triangles are similar as per problem description, so the ratios match:
y/5 = 4/3
x/3 = 9/5
let's solve:
y/5 = 4/3
3y/5 = 4
3y = 20
y = 6.(6)
x/3 = 9/5
5x/3 = 9
5x = 27
x = 5.4
