Juliette [100K]3 years ago
5 0

Answer:

see bottom

Step-by-step explanation:

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

I need help with this, i did part of it but i'm desperate
Nostrana [21]

Answer:

Let's add more steps.

step 6: angle AEB measures 360 - 90 -90 - 70 - 39 = 71° Reason, AECF is a quadrangonal and three of its angle measures 90, 90, and (70+39)

step 7: angles AEB and ABE are congruent: reason triangle ABE is isosceles since AE is conruent to AB

step 8 Angle BAE measures 180 -71-71 = 38°: by difference from the sum of the internal angles.

step 9: Angle BAD measures 90 - BAE = 90 - 38 = 52° Reason angles BAD and BAE are complementary.

Trevor has $92 witch is 4 times as much money as Hannah has how much money does Hannah have
Orlov [11]

Answer: Hannah has $23

Step-by-step explanation: If Trevor has $92 and we know that it's 4 times as much money as Hannah, we can find out how much money Hannah has.

To find how much money Hannah has, we divide how much money Trevor has by 4 since he has 4 times as much money has Hannah.

92 ÷ 4 = 23

Therefore, Hannah has $23 dollars.
