P+(2p-250)=2858 where p equals East High School's population
simplify (combine like terms)
3p-250=2858
add 250 to each side of the equation
3p=3108
divide each side by 3
p=1036
1036 students attend East High School.
Dear Dollster444, the sum of angles Y and Z is bigger than Y.
Answer:
x = −
4 ± √
10,
Step-by-step explanation:
2(x + 4)² = 20
=> 2(x + 4) (x + 4) = 20
=> 2x + 8 (x + 4) = 20
=> 2x² + 8x + 8x + 32 = 20
=> 2x² + 16x + 32 = 20
=> 2x² + 16x + 12 = 0
=> Now solve using the quadratic formula:
x = −
4 ± √
10,
Radical form: −
4 ± √
10,
Decimal form: -0.84, -7.16
Hope this helps!
Just divided the numerator(the top number) by the denominator(bottom number)
