Answer:
x = -6/5 and x = 2
Step-by-step explanation:
y = -10x² + 8x + 24
0 = -2(5x+6)(x-2)
5x+6 = 0 x-2 = 0
5x = -6 x = 2
x = -6/5

50+25= 75
(1/2 of 50 is 25)
Answer:
75 gallons
Step-by-step explanation:
Soooooo
they drank 50 gallons and then they drank half as much as they just drank
50/2 =25 -to get half of what they just drank
50 + 25 =75 - the original 50 gallons + half of that.

Marie and Jorge are both trying to lose weight. After 3 months they compared their weight loss. Marie’s weight went from 175 to 150. Jorge’s weight went from 190 to 180. Which statements are true regarding their weight loss? Select three options. WILL GIVE BRAINLIEST +20 POINTS
ill tell em to ya right now
Jorge’s weight change was approximately 5%.
Marie’s weight change was approximately 14%.
Marie had the greater percent change.
Jorge had the greater percent change.
Marie’s weight change was approximately 1.4%.
#edge2021
Answer:
1 ,2, and 3
Step-by-step explanation:
Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10÷190=5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175=14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.

Show that the binomial is a factor of the polynomial. Then factor the polynomial completely.
g(x)=x3−x2−20x; x+4
g(x)=
Answer:
g(x) = x(x - 5)(x + 4)
Step-by-step explanation:
Here the binomial is x + 4, indicating that a root is -4. Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as
g(x) = x(x^2 - x - 20). Since -20 = -5*4,
g(x) = x(x - 5)(x + 4)
Answer:
x(x-5)(x+4)

Answer:
It's 14..... I just took the quiz
By applying the above properties of a kite, the length of line segment BC is equal to: B. 14 units.
The properties of a kite.According to geometry, the adjacent sides of a kite ABCD are always equal and a pair of opposite angles are always equal. Thus, we can logically deduce the following points:
AB = BCCD ≅ ADBy applying the above properties of a kite, the length of line segment BC is equal to 14 units because it's equal to the length of line segment AB.

The price of a car is $22,000, the car is marked down $2,000, what percent is the car marked down?
(This means that the price of the car is decreasing by $2000, remember part/whole x 100)
Answer:
The car is marked down by 9.09090909 %
Step-by-step explanation:
Given
The price of car = $22,000
Markdown amount = $2,000
To determine
what percent is the car marked down
The percent of the car marked down can be determined by dividing the Markdown amount by the price of the car and multiplying the result by 100.
Markdown % = [Markdown amount / The price of car] × 100
=[ 2000 / 22000 ] × 100
= 0.0909090909 × 100
= 9.09090909 %
Therefore, the car is marked down by 9.09090909 %
