Answer:
step by step Explanation:
Since this is a right triangle,
We can find the length b by using the Pythagoras theorem
a2+b2=c2
Plugin the values
→22+b2=62
→4+b2=36
→b2=32
Take the square root of both sides
→√b2=√32
→b=√16⋅2
⇒b=4√2
You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)

the answer is D. dilation cannot be used to prove this
Answer:
The answer is 3, 6.
Step-by-step explanation:
The numbers in the top rows on the left side of the equation is 1, 4 and 2, 2.
1, 4 + 1, 2 = (1 + 2), (4 + 2) = 3, 6
Answer:
15
Step-by-step explanation:
Let x represent the number of algebra problems. Then the number of geometry problems was 27-x and the total working time was ...
2x +5(27 -x) = 90
-3x = 90 -135 . . . . subtract 135
x = -45/-3 = 15 . . . divide by -3
Rob had 15 algebra problems for homework.
