Answer:
x=8
y= 29
Step-by-step explanation:
corresponding angles are congruent
5x+9=4x+17
x=8
vertical angles are congruent
49=y+20
29=y
Answer:
Therefore, the distance between points A and B is approximately equal to 6.4 inches.
Is that big ideas math? Also it is A.
14 miles.....16hours
xmiles.......1hour
14x1=14
14/16=0,88 miles
Answer:
Step-by-step explanation:
Rewrite this equation in standard quadratic form: x^2 + 13x + 4 = 0.
Here the coefficients are 1, 13 and 4, so the discriminant is
b^2-4ac, or 169 - 4(1)(4) = 153
Since the discriminant is + there are two real, unequal roots. They are:
-13 ± √153
x = ------------------
2
x = ----------------
