Answer:
Step-by-step explanation:
Method 1:
First do the operation inside parenthesis
2*(4-3) = 2*1 = 2
Method 2:
Use distributive property: a*(b +c) = a*b + a*c
2*(4-3) = 2*4 - 2*3
= 8 - 6
= 2
The correct answer is C) (5m^50 - 11n^8) (5m^50 + 11n^8)
We can tell this because of the rule regarding factoring the difference of two perfect squares. When we have two squares being multiplied, we can use the following rule.
a^2 - b^2 = (a - b)(a + b)
In this case, or first term is 25m^100. So we can solve that by setting it equal to a^2.
a^2 = 25m^100 -----> take the square root of both sides
a = 5m^50
Then we can do the same for the b term.
b^2 = 121n^16 ----->take the square root of both sides
b = 11n^8
Now we can use both in the equation already given
(a - b)(a + b)
(5m^50 - 11n^16)(5m^50 + 11n^16)
Answer:
y=-5x-2
Step-by-step explanation:
y=mx+b
where m is the slope
y=-5x+b
to solve for b, which is the y intercept, plug in (1,-7)
-7=-5(1)+b
-7=-5+b
-2=b
y=-5x-2
Answer:
ok so first we have to do whats in the brackets then we have to do to exponits so first
(-0.00024414062divided by 0.00390625)^2
-0.06249999872^2
-0.00390624984
Hope This Helps!!!
it's 0.4 while it may look like 4% it's actually 40% of 1
