Answer:
12x² - 2x - 30
Step-by-step explanation:
(3x - 5)(4x + 6)
12x² + 18x - 20x - 30
12x² - 2x - 30

and D. is symmetrical
Step-by-step explanation:
Answer:
a) 0.61
b) 1.06
Step-by-step explanation:
a) v = u + at
12 = 6 + 9.8t
9.8t = 6
t = 6 ÷ 9.8 = 0.612244898
t = 0.61
f) w = ¾(gk)
7.4 = ¾ (9.31k)
9.31k = 7.4 × 4/3
9.31k = 9.86666667
k = 9.8666667 ÷ 9.31
k = 1.059792338
k = 1.06
Answer:
(x+y)² =(x+y)(x+y) Then you FOIL (First, outer, inner, last)
(x+y)² =(x+y)(x+y) = xx + xy + xy + yy [and when you combine like terms] = x² + 2xy + y²
(x+y)3 = (x² + 2xy + y²)(x+y) Then you FOIL (First, outer, inner, last)
(x+y)3 = (x² + 2xy + y²)(x+y) = x2x +2xxy + xy2 + x2y + 2xyy + y2y [and when you combine like terms] = x3 + 3x2y+ 3xy2 + y3
Step-by-step explanation:
1+11 = 12 so 12 is the answer
