Answer:
Option H, 120 units
Step-by-step explanation:
Total rectangle area:
width x length
10 units x 24 units = 240 units
Area of 1 shaded traingle:
A = (height) x (width) / 2
A = (12 units) x (10 units) / 2
A = 120 units / 2
A = 60
Now mutiple A by 2 since we have two shaded regions
60 x 2 = 120
Subtract the entire rectangle area with the shaded area to get the unshdaed area
240 units - 120 units = 120 units
Answer:
107
Step-by-step explanation:
(3+10^2)+4
10^2=10x10=100
3+100=103
103+4=107
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Hello.
The percent decrease in the mass of the pumpkin for this case will be given by:
(100 - (3.9 / 6.5) * 100) =
(100-60) =40%
After carving it, the pumpkin decreases a percent of 40% in the mass.
Have a nice day
Answer:

Step-by-step explanation:
Question: 5 - 7(z+1) = 7(-9-3z)
We multiply the number in front of the bracket first, since that is multiplication.
--> 5 -7z -7 = -63 - 21z
--> -7z -2 = -63 - 21z
Now, we move all the z and all the numbers to each side.
--> -7z +21z = -63 +2
--> 14z = -61
--> z = -61/14
This cannot be simplified further, so z is -61/14.
