Answer:
20
Step-by-step explanation:
We are to determine the lowest common multiple of 4 and 5
the first six multiple of 4 are = 4, 8, 12, 16, 20, 24
the first six multiple of 5 are = 5, 10, 15, 20, 25
the multiple they both have in common is 20
<em>48</em>
60% of 80 is the same as 60% times 80.
60% of 80 =
= 60% * 80
= 0.60 * 80
= 48
We know that:
So,
25.5 and 1.5
AC = 12 cm
BC = 13.5 cm
12 + 13.5 = 25.5 cm
13.5 - 12 = 1.5 cm
Factor {x}^{2}-4x-5x
2
−4x−5.
(x-5)(x+1)=0(x−5)(x+1)=0
2 Solve for x.
x=5,-1x=5,−1
