Yesterday, two friends went into a bank to open savings accounts. Zack started by putting $38 in his account, and he will deposit an additional $387 each week. Jamal made no initial
deposit, but he will add $406 more each week. In a few weeks, the friends will have the same
account balance. How many weeks will that take? What is that account balance?

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

i think it would be c

mark brainliest if im right

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
