Answer: (3x+2)(x+4)
Step-by-step explanation:Explanation:
3x2+10x−8
first multiply
3
with −8
and we get −24
then find two numbers that if we add or subtract we get
+10
and if we multiply we get
−24
and the numbers are
+12
and
−2
then we place those numbers as follow :-
3x2+12x−2x−8
then we group them
(3x2+12x)(−2x−8)
now take the common factor out.3x(x+4)−2(x+4)
then group the numbers outside of the brackets
(3x−2)(x+4)
500 meters per day * 7 days per week = 3500 meters per week.
3500 meters per week * 1/1000 kilometers per meter = 3.5 kilometers per week.
Answer:
The tree is 64.9 ft tall.
Step-by-step explanation:
Think of a right triangle. Draw the right triangle. The tree is a vertical side of the triangle, so it is a leg with unknown length, so call its length y. The ground, is a horizontal leg with length 100 ft. The angle from endpoint of the horizontal leg on the ground away from the tree to the top of the tree is 33º.
For the 33º angle, y is the opposite leg, and 100 ft is the adjacent leg.
The trig ratio that relates the lengths of the opposite leg to the adjacent leg is the tangent.
tan A = opp/adj
tan 33º = y/100
y = 100 * tan 33º
y = 64.9
Answer: The tree is 64.9 ft tall.
Hello!
The equation that represents this situation is A. 3t = 27.
Explanation:
This is because an equation is a "mathematical sentence" and this equation says that if you multiply the costs of the three friends' tickets, the total cost would be $27.
