Kim is x years old . jordan is 7 year older than kim. four times jordans age is equal to 200

write an equation that could be used to solve for kims age x

how old is kim

how old is jordan

plz

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

yes

step-by-step explanation:

yes
