P= parentheses or ()
E= exponents such as

M= multiplying
D= division
A= Addition
S= Subtraction
Another popular acronym is BEDMAS, which is pretty much the same except for division and multiplication are switched and it uses the word Brackets to describe these: ().
(x - 4)(x - 3) + (2 - x)(x - 1)
= x² - 3x - 4x + 12 + 2x - 2 - x² + x
= x² - x² -3x - 4x + 2x + x +12 - 2
= 0 -4x +10
Answer: -4x + 10
Answer:
68°
Step-by-step explanation:
As BA⊥BD, so ∠ABD = 90°
also, ∠ABD = ∠CBD + ∠ABC
⇒ 90° = 4x + 52° + 8x - 10°
⇒ 12x = 48°
⇒ x = 4°
now,
∠CBD = 4x + 52°
= 4(4°) + 52°
= 68°
Answer:
skew
Step-by-step explanation:
Lines a and c are skew
Reason:
1) Because they will never intersect each other.
2) They are not on the same plane.
3) They are not parallel and perpendicular.
Thus the right option is skew....
