Answer:
Step-by-step explanation:
area of rectangle=length×width
=(x²+6x+3)×(3x²+4x-2)
=3x^4+(4+18)x³+(-2+24+9)x²+(-12+12)x-6
=3x^4+22x³+31x²-6
Your absolute value cannot be negative.
144, 4:6 simplifies to 2:3, if you divide 96 by 2 you get 48, and 48 x 3 = 144
The other expression that has a value of
is A) sin B.
Step-by-step explanation:
Step 1:

For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.

Step 2:
For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.
Step 3:
tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.
So sin B also has a value of
This is option A.
Y=(x+3)²+(x+4)²
y=x²+6x+9+x²+8x+16
y=2x²+14x+25
y=2(x²+7x+3.5²-3.5²)+25
y=2(x+3.5)²-2*3.5² +25
y=2(x+3.5)²+0.5
