9 miles because 3/4 x 3 is 2.25 then multiply 2.25 and 4
Answer:
x=-2 and -32/3
Step-by-step explanation:
|3x+19|=13
3x+19=13 and 3x+19=-13
x=-2 and x=-32/3
3 increased by the product of 4 and 12 is 3 + (4 * 12)
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
Combined speed = 95+75= 170 mph
they will meet in 306/170 = 1.8 hours or 1 hour 48 minutes.
