Answer:
7/2 =x
Step-by-step explanation:
The triangles are similar so we can write a ratio to solve
2 4
---- = -------
x 7
Using cross products
2*7 = 4x
14 = 4x
14/4 = 4x/4
7/2 =x
The third option is the answer
Step-by-step explanation:
First you do 3a^4(2b^6c^3)^2
=12a^4b^12c^6
X=15
EXPLANATION:
5x+4+5x+11+x=180
11x+15=180
-15 -15
11x=165
— ——
11 11
x=15
C. I used the app math way. it has been a lifesaver.
