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
Answer
given,
a) x-1=0
adding both side with 1
x = 1
b) x + 1 =0
subtracting both side by 1
x = -1
c) x²- 1 =0
x² = 1
taking square root
x = √1
x = 1
d) x²+ 1 =0
x² = -1
taking square root
x = √-1
x = i (iota)
Answer: A and C are the correct answers
