Let N be the length of the real house.
To solve, write the equation in ratio -
2/4 = N/17
2(17) = 4(N)
34/4 = 4N/4
N = 8.5
Therefore, the length of the real house is 8.5
Answer:
Step-by-step explanation:
Answer:
We want to expand the expression:

We can just do it by brute force, this is:
First, rewrite our expression as the product of two square factors:

Now we can expand each one these two factors:

That can be simplified to

Now we can replace that in our original expression to get:

Now we can expand that last product, to get:

We can simplify that to:

That is the expanded expression.
Answer:
38 degrees.
Step-by-step explanation:
There are 180 degrees in a triangle, so
m<1 = 180 - (43 + 74)
= 180 - 117
= 63 degrees.
m < 2 = m < 1 ( opposite angles) so
m < 2 = 63 degrees.
Finally, m < 3 = 180 - (63 + 79)
== 180 - 142
= 38 degrees.
