5 * (2 + 4)
5 * 2 + 5 * 4 (the distributive property)
5 * 6 (order of operations)
Answer:
x^2 + 10x + 25
Step-by-step explanation:
(B/2) ^2
10/2 = 5
5^2 = 25
A perpendicular bisector forms two right angles and splits the line in two equal parts.
The altitude does create two right angles, but doesn't have to create two equal parts.
Answer:
Step-by-step explanation:
Using sine rule
SinA/a = SinB/b = SinC/c
A = 84° a = BC, C = 51°, c = 16
Sin84/BC = Sin51/16
Cross multiply
BC Sin51 = 16 × Sin84
BC = 15.91/Sin51
BC = 20.48unit
Answer:
x = 6 lb
Step-by-step explanation:
Let
Total weight of the candy = x
3/20x + 1.2 lb + 3/5x + 0.3 lb = x
3/20x + 3/5x + 1.5 lb = x
3x+12x/20 + 1.5 lb = x
15/20x + 1.5 = x
1.5 = x - 15/20x
1.5 =20x -15x /20
1.5 = 5/20x
1.5 = 1/4x
x = 1.5 ÷ 1/4
= 1.5 × 4/1
= 6
x = 6 lb
