You have to multiply 36 times 4 =144 . So you do this like this (30 times 4) +(4 times 6)= so (120)+(24)= 144. Answer is 144
Use distance formula to find the distance between vertices to get side lengths.
add these lengths
Answer:
a = 2 ; b = -3 ; c = -20
Step-by- step explanation:
Use FOIL method.
(2x + 5)(x - 4) = 0
2x*x+ 2x*(-4 )+ 5*x + 5* (-4) = 0
2x² - 8x + 5x - 20 =0
Combine like terms,
2x² - 3x - 20 = 0
Standard form: ax² + bx + x = 0
a = 2
b = -3
c = -20
12/5, because 3*4 is 12 and then it 12/5
Answer:
-3/2
