Answer:
(9)(m)
Step-by-step explanation:
We can obtain the right answer to question as follow:
m – 9
We can not carryout the operation because m and 9 has nothing in common.
9 + m
We can not carry out the operation because 9 and m has nothing in common.
(9)(m)
Thus, (9)(m) can be written as
(9)(m) = 9 × m
We can carryout the operation since 9 can multiply the coefficient of m i.e 1 as shown below:
9 × m = 9 × 1m = 9m
Thus,
(9)(m) = 9m
From the above illustrations, we can see that (9)(m) is equivalent to 9m
Answer:
60
Step-by-step explanation:
Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.
A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.
Answer:
y = 2x + 1
Step-by-step explanation:
1. Find the slope; (change in y values)/(change in x values)
Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2
2. Find the y-intercept (b) using the slope intercept formula: y = mx + b
m = 2 and using point (1, 3) , solve for "b"
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
3. Write the linear equation: y = 2x + 1
Answer:
( P -2w) /2 = l
Step-by-step explanation:
P= 2W + 2l
Subtract 2W from each side
P= 2W -2W + 2l
P -2W = 2l
Divide by 2
( P -2w) /2 = l
