F(x)=-2(x-3)(x+5) convert quadratic functions to standard form​
jasenka [17]

Answer:

The answer is: f(x) = -2x^2 - 4x + 30

Step-by-step explanation:

Given:

f(x)=-2(x-3)(x+5)

Solve (x-3)(x+5) first, then multiply by -2:

f(x) = -2[(x - 3)(x + 5)]

f(x) = -2[x^2 -3x + 5x - 15]

f(x) = -2[x^2 + 2x - 15]

f(x) = -2x^2 - 4x + 30

nirvana33 [79]
I think it's 138 Long by 109.5 more accurate .
92/73 = 1.26
120/100 = 1.2
138/109.5 =1.26
Hence 138 by 109.5 is more proportionate

Someone help, I'm really bad at geometry
jeka94
Use linear pairs to find the measure of angle B and the measure of the angle adjacent to the measured angle 135. Use the vertical angle theorem to find that angle inside the triangle across from B. Then use the triangle angle sum theorem to add up your values to equal 180. Solve for x and then plug that value back into 31 +x.

A jet traveles 520 miles in 5 HOURS all this rate how far can the jet fly in 14 hours what is the rate of speed of the jet?
frosja888 [35]
To find the speed of the jet, divide the distance by time.

520/5= 104 mph

Speed = distance / time

So 104 = distance / 14

Distance = 104*14=1456 miles
