Answer:
A = 42 cm²
Step-by-step explanation:
the area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
here b = 6 and h = 7 , then
A = 6 × 7 = 42 cm²
4x²-12x+9=5
4x²-12x+4=0
x= 12±√(144-4*4*4) / 2*4
x= 12 ± √(144-64) / 8
x=12±√80. /. 8
x= 12+4√5. /8
x=3±√5 / 2. C and E
P = 6s
s = 3.4
P = 6(3.4) = 20.4 cm
This indicates that 5/2 is less than -1 on the number line.
