Answer:
x = 13
Step-by-step explanation:
There are two ways to do this. You could use the Pythagorean Theorem because you are given that the triangles are right angled triangles.
Method One
a^2 + b^2 = c^2
a = 5
b = 12
c = ?
c^2 = 5^2 + 12^2
c^2 = 25 + 144
c^2 = 169
sqrt(c^2) = sqrt(169)
c = 13
x = 13
Method Two
You can do this problem with similar triangles.
48/12 = 52/x Cross multiply
48x = 12 * 52 Combine the right
48x = 624 Divide by 48
48x/48 = 624/48 Do the division
x = 13
Answer:
-3.2
Step-by-step explanation:
4 times .5 is 2. Then .4 times 3 is 1.2. add 2 and 1.2 and get 3.2.
Hope this helps and good luck :)
The answer is D, I believe at least.
2(
x + 4) = 
x + 4 which is the second option is the equivalent expression.
Explanation:
First, we need to calculate the value of two-fifths of x. It means 2 portions out of the five portions of x which equates to x.
Now we calculate the values of the two expresssions on the LHS.
1) 2 (two-fifths x + 2) = 2 (x + 2) = x + 4.
2) (two-fifths x + 4) = 2(x + 4) = x + 8.
Now we determine values of the four expressions on the RHS.
1) Two and two-fifths x + 1 = 2x + 1
2) Four-fifths x + 4 = x + 4
3) Four-fifths x + 2 = x + 2
4) Two and two-fifths x + 8 = 2x + 8.
Out of the various LHS and RHS values, the 
LHS value and 
RHS value is the same. So option 2 is the answer.
