4(x−0.8)=3.8x−5.8 PLZZZ ANSWER FAST!
Hunter-Best [27]
To find the answer:
4(x - 0.8) = 3.8x - 5.8 \\ 4x - 3.2 = 3.8x - 5.8 \\ 4x - 3.8x =  - 5.8 + 3.2 \\ 0.2x =  - 2.6 \\ x =   - \frac{ 2.6}{0.2}  \\ x =  - 13

Therefore, x=-13.

Hope it helps!

Help! Have no clue how to do. Will give Brainly thing if someone helps
stiv31 [10]

Answer:

h = 18( I might be wrong though)

Step-by-step explanation:

If BE and ED are perpendicular, that means this angle is supplementary.

BEF = 3h-12

FED = 2h - 23

BEF + FED = 90

3h-12 + 2h - 23 = 90

5h - 35 = 90

5h = 90

h = 18 degrees
