Try A I believe that’s right
Answer:
It seems that your options aren't correct as the right answer is -5.3333... (recurring)
Step-by-step explanation:
1) 2x + 4 = 20 + 5x (subtract by the smallest unknown)
-2x -2x
2) 4 = 20 + 3x
-20 -20 (now subtract each side by 20 as we want to leave the unknown on one side and another number on the other side.
3) -16 = 3x (Divide each side by 3)
÷3 = ÷3
4) -5.33333... = x
<h3>Now we have found x but if you're unsure you can substitute to see if your answer is correct.</h3><h3>2 x -5.3333 + 4 = -6.6666</h3><h3>20 + 5 x -5.3333= -6.6665</h3><h3>Our answer is correct! (When answers are rounded, it is equal to the same thing).</h3>
Answer:
The bottom one
Step-by-step explanation:
the lowest dot is on -3 so that's the y-intercept
the other is at 2 x and -1 y
Answer:
the first one is 8 and 9
the second one is 13 and 14
Step-by-step explanation:
8^2 is equal to the square root of 64 and 9^2 is equal to the square root of 81.
13^2 is equal to the square root of 169 and 14^2 is equal to the square root of 196.
hope this helps and is correct.
Answer:
28
Step-by-step explanation:
To find the area of a rectangle we multiply two edges together.
since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)
ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal
2(1x2) + 4(3x2) = 4 + 24 = 28
