Answer:
x =(-4-√96)/10=(-2-2√ 6 )/5= -1.380
x =(-4+√96)/10=(-2+2√ 6 )/5= 0.580
Step-by-step explanation:
Answer:
The answer is the 3rd one.
Step-by-step explanation:
3 times 3 is 9
4 times 4 is 16
13 is in between those 2 numbers
Just multiply directly numerator with numerator and denominator with denominator
For the bottom, to find the top side of the triangle, 10-4, as seen from the top and bottom sides of the rectangle. So 6.
To find the left side of triangle, subtract 12 from 8. 12 from the left and 8 from the rectangle. This gives you 4.
Now that we have 6 and 4, we can find the area:
A= ab/2
A= (6*4)/2
A=24/2
A=12 mm^2

Answer: 14</h2>
Step-by-step explanation:
If we factorize the numbers, we may be able to surmise the GCF:
28 = 2 × 2 × 7
42 = 2 × 3 × 7
56 = 2 × 2 × 2 × 7
∴ the GCF is 2 × 7 = 14
