(16x+4)(2x+5)
Step-by-step explanation:
Answer: width = 82.50 m
Step-by-step explanation:
P = 2l x 2w
425 = 2(130) + 2w
425 - 260 = 2w
w = 165 / 2 = 82.50
Then there would be 9 girls and 23 boys

Answer:
x = -3+√5, -3-√5 (exact roots)
or x = -0.76, -5.24 to the nearest hundredth.
Step-by-step explanation:
x² + 6x = - 4
Completing the square:
(x + 3)^2 - 9 = -4
(x + 3)^2 = 5
x + 3 = +/-√5
x = - 3 + √5, - 3 - √5
