Answer:
In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.
The full correct process is:
(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15
= 4m - 6m + 9 + 15
= -2m + 24
Answer:
D
Step-by-step explanation:
SQUARES BECAUSE THEY ARE IN THE MIDDLE DUMMY
-2/3x+3/7=0.5
-2/3x+3/7=5/10
-2/3x+3/7=1/2
-42 x 2x +6 x 3=21
-28x+18=21
-28x=21-18
-28x=3
x=-3/28
Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB
units [By distance formula :
]
units
Width = BC =
units

Area = length x width
= 
Hence, the area of the rectangle is 82 sq. units .
