Answer:[tex]y=-4x^2 -8x-6
Step-by-step explanation:
IF IT EQUALS 0
1. find two number that multiplied to 48 and adds to 14, which are 6 and 8.
2. substitute the new numbers in with x to get x^2 + 6x + 8x + 48.
3. factor out the x and the 8 to get x(x+6)+8(x+6).
4. x = -6, x = -8
IF IT DOES NOT EQUAL 0
then (x+6)*(x+8) is your answer.
Angle 2 is 143
angle 4 is 37
angle 7 is 143
angle 8 is 37
Answer: length = 27 cm
Step-by-step explanation:
Perimeter = 2(l + w)
86 = 2(l + 16)
86 = 2l + 32
86 - 32 = 2l
l = 54/2 = 27 cm.
