Answer:
104
155
180
Step-by-step explanation:
an easy way is to solve what is in the parenthesis then multiply by the outside number
but if you need to use the distributive property:
1. 4 x (20 - -6)
(4 x 20) - (4 x -6) = 80 - -24 = 80 + 24 = 104
2. -5 x (24 - -7)
(-5 x 24) - (-5 x -7) = -120 - 35 = 155
3. 12 x (-30 + 45)
(12 x -30) + (12 x 45) = -360 + 540 = 180
Is this even answerable, because u would need to figure out what ‘b’ is to figure out the answer
Answer:
2.8
Step-by-step explanation:
If u divide 14 into 5, you get a decimal, 2.8.
we have the function
y=f(x)=x^2
the domain is all real numbers -------> interval (-∞, +∞)
the vertex of the vertical parabola is the origin (0,0)
the parabola opens upward
the vertex is a minimum
so
the range is the interval [0, ∞)
Answer:

Step-by-step explanation:
7-4=3
now let's change the denominator by finding the lcd (lowest common denominator)
<em>factors of 3:</em> 3, 6, 9, 12...
<em>factors of 6:</em> 6, 12, 18, 24...
both 3 and 6 has 6 as their lcd
3 x 2= 6
1/6 -4/6= -3/6
REDUCE
-1/2
3-1/2
2 1/2
