Answer:
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.
Step-by-step explanation:
To find the slope use the formula
Y2-Y1
---------
X2-X1
(-1,-4) (1,4)
4- -4 = 8
-------------
1- -1 = 2
8/2=4 This will be your slope
Y=4x
Now we must figure out the y-intercept using the formula
Y-y1=slope(x-x1)
Y- -4= 4(x- -1)
Y+4= 4x + 4 The 4 distributes to the x and -1
Y=4x +4
-4
Y= 4x
This is your answer in slope intercept form.
P.S if you have a number minus a negative number it makes it a positive number
Answer:
0,0
2,-1
-2,4
Step-by-step explanation:
The correct answer is actually choice D.
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
