<h2>
The equivalent expression of 25 - 64 are "a), b) and c)".</h2>
Step-by-step explanation:
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
= 25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
= 25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) =
=
= 25 - 64, is the equivalent expression.
d) ( + 13)( - 13)
Using the algebraic identity,
(a + b)(a - b) =
=
= - 169, is not a equivalent expression.
e)
Using the algebraic identity,
, is not a equivalent expression.
∴ The equivalent expression of 25 - 64 are "a), b) and c)".
Answer:
4
Step-by-step explanation:
10 - 2 = 8
4 x 2 = 8
4 x 3 = 12
Answer:
1/4 or or 0.25
1Step-by-step explanation:
just do 2.75 divided by 11 and you get your answer
Answer:
56x-42x+63
Step-by-step explanation:
1) Converting true bearing to quadrant:
a) 140 degrees.
Taking North as origin, it would be:
E50S
So, final answer for this part is E50S
b) 94 degrees
Taking North as origin position, it would be: E04S
So, final answer for this part is E04S
2) Converting to true-bearing:
a) S50W = from north, it would be: 180+ 50 = 230 degrees
So, 230 degrees is the answer.
b) N15W = from north, in anti-clock wise direction (direction in which we usually calculate) would be: 360-15 = 345
So, 345 degrees is the answer.
Hope this helps!
