Answer:
its a right angle and a its an acute angle as well so it be 5
we start by opening the brackets so it will be -25 plus 15 v is equals to 115. negative times a negative is a positive so -5 times -3 we we have gotten positive 15v there I hope you understood so our new equation is -25 + 15v is equals to 115 collect the like terms 15v is equals to 115 + 25 15 v is equals to 140 divide both sides by 15 so v is equals to 9 and 1/3
Answer:
A figure has rotational symmetry if it can be rotated by an angle between 0° and 360° so that the image coincides with the preimage.
Step-by-step explanation:
Johan ran 7.25 miles every hour for 5 hours
Step-by-step explanation:
9(x+1) = 25+x
open the bracket
9x + 9 = 25+x
collect like terms
9x-x = 25-9
8x = 16
x = 2
