Answer:
30 ft
Step-by-step explanation:
We can use ratios
3 6
------ = ------------
15 x
Using cross products
3x = 6*15
Divide each side by 3
3x/3 = 6*15/3
x = 30
<span>2x-1/4(12x+4)=3
</span>⇒ 2x -1/4*(12x) -1/4*4= 3 (distributive property)
⇒ 2x -3x -1= 3
⇒ -x= 3+1
⇒ -x= 4
⇒ x= -4
<span>
Final answer: x=-4~
</span>
The answer is option C:
<span>A line of symmetry will connect a vertex and a midpoint of an opposite side.
It has 7-fold symmetry.</span>
5. A
6. No, 1/5(25x+15)-7x= -2x+3
-2(x-5)= -2x+10
-2x+3 is not equal to -2x+10
Answer:
13. It is a paralellogram, because its opposite sides are equal & parallel
14. It is a paralellogram , because it's two diagonals bisect each other .
15. Is a paralellogram, cause its opposite angles are equal
