Step-by-step explanation:
An unknown number minus 8.
Answer:
1.) step No.3 x(2x-5) - (2x-5)
2.) 16 +28i-28i - 49i²
but we know i² = -1
the expression becomes
16 + 49
= 66
Answer:
Area of ΔDEF = 12 in²
Step-by-step explanation:
Since they are similar, we have to find the scale factor
Scale Factor = 
Scale Factor = 4/2
Scale Factor = 2
<u><em>This means The area of ΔABC is 2 times the area of ΔDEF</em></u>
So,
ΔABC = 2(ΔDEF)
Where Area of ΔABC = 24 in²
24 = 2(ΔDEF)
Dividing both sides by 2
=> Area of ΔDEF = 12 in²
