Answer:
3 cm by 10 cm
Step-by-step explanation:
Assuming the new dimensions are integers, we can look at the factors of 98 to see what they might be.
98 = 1·98 = 2·49 = 7·14
The latter two factors differ by 7, so are the dimensions after 4 is added. The original dimensions are ...
7 - 4 = 3 . . . . cm
14 -4 = 10 . . . . cm
The dimensions of the original rectangle are 3 cm by 10 cm.
y = - 5
substitute the value of x = 4 into the equation and solve for y
- 12 + 9y = - 57 ( add 12 to both sides )
9y = - 45 ( divide both sides by 9 )
y = 
= - 5
Answer:
The one that is on the bottom half and on the right side.
Step-by-step explanation:
(0,30) to (10,0)
Because the x value 0 represents the time in which the paint job started and ends in the value 10
While the y value 30 is the amount of paint he started with and ends with 0
<u><em>Answer:</em></u>
-9
<u><em>Explanation:</em></u>
<u>From the first three </u><span><u>triominoes, we can note that:</u>
number on center = -first base - second base + vertex
<u>This is verified as follows:</u>
<u>For the first one:</u>
The two bases are 7 and 9 and the vertex is 1
- first base - second base + vertex = -7 -9 + 1 = -16 + 1 = -15
<u>For the second one:</u>
The two bases are 0 and 9 and the vertex is 8
- first base - second base + vertex = -0 -9 + 8 = -9 + 8 = -1
<u>For the third one:</u>
The two bases are 6 and 4 and the vertex is 2
- first base - second base + vertex = -6 - 4 + 2 = -10 + 2 = -8
<u>Applying the same procedure on the last one:</u>
The two bases are 7 and 2 and the vertex is 0
-first base - second base + vertex = -7 - 2 + 0 = -9 + 0 = -9
Hope this helps :)</span>
