Answer:
36
Step-by-step explanation:
base=12
height=3
3 times 12 equals 36
36 sq ft
A=bh
A=(12)(3)
A=36
-1
the coordinates are (1,6)(4,3)
lets say that
x1=1
x2=4
y1=6
y2=3
slope formula: (y2-y1)/(x2-x1)
= (3-6)/(4-1)
= -3/3
= -1
the answer is
12 = y - 5
y=17
x+2 = 4
x=2
Mean:
Median: 63, 66, 67, 68, 73, 74, 76, 78, 80, 83, 86, 87, 88, 89, 89, 89, 93, 93, 95, 99, 100
= 169/2
Mode: 100
4cm, 11cm, 21cm
4(x + 1)(x + 11)
4(x ^ 2 + 12x + 44)
x ^ 2 + 12x + 11 = 231
x ^ 2 + 12x + 11 - 231 = 0
x ^ 2 + 12x - 220 = 0
(x - 10)(x + 22) = 0
x = 10 and x = - 22
4cm , 11cm , 21cm
Hope it helps you xx
