Solve (x + 3)^2 + (x + 3) – 2 = 0.
let u = x+3
rewrite the equation in terms of u.

a. u^2 + u – 2 = 0

b. (u^2 + 9) + u – 2 = 0

c. u^2 + u + 1 = 0

Which triangle congruence postulate or theorem justifies my claim that the steps i made using construction paper and scissors produce an isosceles triangle? was it sss, sas, asa, aas, or hl?

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
