1/8= 1/8
3/4= 6/8
1/8 + 6/8 = 7/8
Keep these rules in mind:
- (a + b)² = a² + 2ab + b²
- (a - b)² = a² - 2ab + b²
- (a + b)(a - b) = a² - b²
Firstly, solve the exponent and multiplication:
Next, combine like terms:
Next, subtract 4x² on both sides:
Next, subtract 25 on both sides:
Lastly, divide both sides by -20.5. And since you are dividing by a <u>negative</u>, flip the inequality sign:
<u>Your answer is x > 2.</u>

Answer:
the number of students who do not delve in any of the 2 areas is 220
Step-by-step explanation:
The computation of the number of students who do not delve in any of the 2 areas is shown below:
= Total students - maths students - english students - both subject students
= 900 - 350 - 220 - 110
= 220
Hence, the number of students who do not delve in any of the 2 areas is 220
Answer:
61
Step-by-step explanation:
This composite function can be easily solved
First solve f(-2)
f(-2)=(-2)³+3
f(-2)=-8+3=-5
Now plug -5 for x in function g(x)
=2(5)²+2(5)+1
=50+10+1
=61
