∆ABC and ∆FDE are congruent by the SSS
criterion.
x + 3 = 14 |subtract 3 from both sides
x = 11
subtitute the value of x to the equation x - y = 3
11 - y = 3 |subtract 11 from both sides
-y = -8 |change the signs
y = 8
Answer: x = 11 and y = 8.
Answer:
1728 m^3.
Step-by-step explanation:
As all the sides of a cube are , by definition, equal the answer is 12^3
= 1728 m^3.
Answer:
<h2><u><em>
1/4 + 9/12 = 1</em></u></h2>
Step-by-step explanation:
1/4+9/? =1
1/4 + 9/<u>12</u> = 1
<u><em>9/12 = 3/4</em></u>
<u><em>1/4 + 3/4 = 1</em></u>
Answer:
-20 =r
Step-by-step explanation:
4r - 8 = 5r + 12
Subtract 4r from each side
4r -4r- 8 = 5r + 12-4r
-8 = r+12
Subtract 12 from each side
-8-12 = r+12-12
-20 =r
