<span>A technique for mental multiplication is called factoring the tens which relies on the fact that 10*n, for any real number n. This will make the problems easy to compute. 6 x 2 = 12 is a memory value. </span>
12 x 10 = 120
12 X 100 = 1200
Take for instance in 6 x 2, 6 x 20 and 6 x 200. Find the factors and these are the computations. We can also say:
<span>6 x 20 = 6 x 2 x 10 = 12 x 10 = 120
60 x 20 = 6 x 10 x 2 x 10 = 12 x 10 x 10 = 1200</span>
It must be remembered that in the commutative and associative properties of multiplication, the order of the factors does not matter when solving this kind of problem

D part
Step-by-step explanation:
3x + 80⁰ + 2x = 180⁰ (By Linear Pair)
5x + 80⁰ = 180⁰
5x = 100⁰
x = 20⁰
Hope it helps :)
Step-by-step explanation:
area of rectangle = l × h
= 9 × y
= 72
9 × y = 72
y = 72÷9
y = 8cm
area of circle = 50.27cm²
total area of the logo = 2(50.27) + 72
= 100.54 + 72
= 172.54cm²
