Triangle DEF is dilated to create triangle DAB. What scale factor was used? please hurry in less than 10 min

Not sure how you would word it but the bigger triangle is 2 times larger than DEF.

Step-by-step explanation:

DE=4

AE=4

4+4=8

AD=8

Hope this helps!!

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
