Answer:
Step-by-step explanation:
The not simplified form is 
you know that 
is true a and b are both positive or one of it is negative (not both of them).
You can write -44 as -1 × 4 × 11 inside square root.
So, 
(

(NOTE : You must know that 
is written as 
)
Answer:
1 and 5. Can I get a brainliest???
Step-by-step explanation:
given:
x² + 12x = 11
perfect square:
a² + 2ab + b²
a² = x² ⇒ x * x
2ab = 12x ⇒ 2(6)x
b² = 6² ⇒ 36
x² + 12x + 36 = 11 + 36
(x+6)(x+6) = 47
Both sides must be added with 36.

Answer:
all 4 acute angles: 15 degrees
all 4 obtuse angles: 165 degrees
Step-by-step explanation:
The sum of same-side interior angles between parallel lines is 180°. The smallest of them will be 3/(33+3) = 1/12 of 180°, or 15°. The largest will be 180° -15° = (33/3)(15°) = 165°. All remaining angles are congruent to one or the other of these.
All four acute angles are 15°; all four obtuse angles are 165°.
Answer:
Step-by-step explanation:
radius of a coin is 12 mm
Diameter of the coin is twice the radius = 2 x 12mm = 24mm
The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m
Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²
what is the area of the coin
