Answer:
x=4
Step-by-step explanation:
4(3+2x)+2=46
12+8x+2=46
12+8x=44
8x=32
x=4
okay so you should know that the formula for a triangle is:
A=1/2×b×h
where b is breadth and h is height
A is area
so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)
so we put these into the equation of the area of a triangle
A=1/2×b×h
16.2=1/2 × 6 × h
then you will solve algebraically to get 5.4cm which is you answer
to check if correct you can always put in all numbers in equation and you should get 16.2cm
In this case it's correct ✌
Answer:392.5
Step-by-step explanation:

Answer:
3 necklaces and 12 bracelets
Step-by-step explanation:
Bracelets = x +4
amount of necklace gold = 20*x
amount of gold in bracelet = 7*(x+4)
added together = 109 gm
20x + 7(x+4) = 109
20x + 7x+28 = 109
27x+28=109
-28 -28
27x= 81
/27 /27
x=3 necklaces
then bracelets = 3+4=12
