Answer:
Step-by-step explanation:
In exponential multiplication, if bases are same, add the powers
xᵃ * xᵇ = xᵃ⁺ᵇ
Side = 12d⁶e⁷
Area of square = side *side
= 12d⁶e⁷ * 12d⁶e⁷
= 12* 12* d⁶e⁷ * d⁶e⁷
= 144d⁶⁺⁶ * e⁷⁺⁷
= 144d¹²e¹⁴
Answer:
Step-by-step explanation:
1). ∠7 ≅ ∠ 2 (alternate exterior)
m∠7 = m∠2 = 30°
2). ∠4 and ∠1 are supplementary angles
m∠1 = 180° - 72° = 108°
No
A number that doesn’t have any sign in front of it is naturally considered as positive.
But, negative numbers should have a negative sign in front of them though.
