Answer:
(x+2)(x+4)
Step-by-step explanation:
Answer:
Basically you add all the numbers shown there and divide by how many there are. So you just get the sum and divide that by 11 since there are 11 numbers. Happy to help! (mean)
Step-by-step explanation:
Answer:
25 (with assumptions)
Step-by-step explanation:
ASSUMING ES=SD and FT=TG, then the difference between EF and ST is the same as the difference between ST and DG. Since ST - EF = 19 - 13 = 6, then DG - ST = 6 or DG - 19 = 6, add 19 to both sides and DG = 25
Answer:
x = 3 or x = -3
Step-by-step explanation:
Solve for x over the real numbers:
2 x (x + 3) - 6 (x + 3) = 0
Expand out terms of the left hand side:
2 x^2 - 18 = 0
2 x^2 - 18 = 2 (x^2 - 9):
2 (x^2 - 9) = 0
Divide both sides by 2:
x^2 - 9 = 0
x = (0 ± sqrt(0^2 - 4 (-9)))/2 = ( ± sqrt(36))/2:
x = sqrt(36)/2 or x = (-sqrt(36))/2
sqrt(36) = sqrt(4×9) = sqrt(2^2×3^2) = 2×3 = 6:
x = 6/2 or x = (-6)/2
6/2 = 3:
x = 3 or x = (-6)/2
(-6)/2 = -3:
Answer: x = 3 or x = -3
