Answer:
Step-by-step explanation:
If ΔABC ~ ΔDEF
Then their sides must be proportional such that:
=> 
Cross Multiplying
=> x * 6 = 8*3
=> 6x = 24
Dividing both sides by 6
=> x = 4
Answer:
7g+5 I'm pretty sure
Step-by-step explanation:
6g+g=7g 9-4=5
so it's 7g+5 simplified
To solve this, you need to subtract 180 from 400: (400-180=220). After that (I used the fraction/proportion/variable way, but there are others), so 220/400=%(p)/100. Multiply diaganolly, so 400*p=400p, which is equal to 220*100=22000. Therefore, 400p=22000. Now, you have to isolate the variable by dividing both sides by 400: 400p/400=p, and 22000/400=55. Therefore, p=55, or %=55, so the answer is 55%, or C.
Answer:
88 cm²
Step-by-step explanation:
The perimeter of each square is 22 cm
we should divide by 4 to get the length of the square
22/4=5.5 cm
so we should multiply by 2 to get the length of the rectangle
5.5*2= 11
the perimeter is :
P= 5.5+5.5+5.5+11+11+5.5+5.5+11+11+5.5+5.5+5.5 = 88 cm²
