Answer: -3
Step-by-step explanation: 2x = -2 then you subtract 1 from that which is the same as adding negative one so -2 - 1 or -2 + -1 = -3
Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
Answer:
Step-by-step explanation:
For perpendicular lines, we use the same y-intercept. Though, to find the slope of perpendicular lines, we use opposite reciprocals. The opposite reciprocal of 
is 
.
Answer: Multiply the number(s) outside the parenthesis by the numbers inside the parenthesis. The distributive property is expressed in math terms as the following equation: a(b + c) = ab + ac.
Step-by-step explanation:
2(3 + 4) - 12 Multiply 2 times 3 first.
2 x 3 = 6.
Then multiply 2 times 4.
2 x 4 = 8.
Remember our equation earlier? a(b + c) = ab + ac.
In this case, 2 is a, 3 is b, and 4 is c.
So 2[a](3[b]+4[c]) = 2[a](3)[b] + 2[a](4)[b].
Let's rewrite this in a way that can be read better.
2(3+4) - 12 = 2(3) + 2(4) - 12.
2(3+4) - 12 = 6 + 8 - 12.
2(3+4) - 12 = 14 - 12.
2(3+4) - 12 = 2.
Hope this helped! :)
