Answer:
Step-by-step explanation:
3 pieces such that each piece is 2 cm longer then the next...
x , x + 2, x + 4
x + x + 2 + x + 4 = 30
3x + 6 = 30
3x = 30 - 6
3x = 24
x = 24/3
x = 8
x + 2 = 8 + 2 = 10
x + 4 = 8 + 4 = 12
check...
8 + 10 + 12 = 30
18 + 12 = 30
30 = 30 (correct)...it checks out
the ribbon lengths are : 8 cm, 10 cm, and 12 cm
Inside the root is 50-1
50-1 = 49
You would remain with root 49 but, if you calculate the square root the answer would be 7 because...
7•7 = 49
^ So, the answer is 7
First off both triangles form a 90° angle there both congruent. you can tell they form a 90° angle because of square box
The value of expression is 7.
<h3>What is expression?</h3>
An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)
Given:

Now, using property of log
a log b
So,
= 7 log 10
As log 10 = 1
= 7 (1)
= 7
