Answer:
A
Step-by-step explanation:
Use foil to expand it.
y = 4 (x^2 + 7x - 9x - 63) Combine the like terms on the right.
y = 4(x^2 - 2x - 63) Use the distributive property to remove the brackets.
y = 4x^2 - 8x - 4*63 Combine the two multiplied factors on the right.
y = 4x^2 - 8x - 252 4* 63 = 252
The answer is A
Answer:
-4 1/2, -4.3, 15%, , 2 1/4
Step-by-step explanation:
Because -4 1/2= -4.50, -4.3 is next, 15%=0.15, =2.24, and 2 1/4= 2.25
Right Angle - 90 Degrees
A+B+C = 180
90+B+51 = 180
141 + B = 180
B = 39
