X= √2 , -√2
or x ≈ 1.41 , -1.41
I hope this helps ya out :)
Answer:
48 + 18√13 cm²
Step-by-step explanation:
HC = BC/2 = 4m/2 = 2 m
AC = √AH² + HC² = √9 + 4 = √13
A = 2×A(ABC) + 2×A(ACFD) + A(BCFE)
= 2×AH×BC/2 + 2×AC×CF + BC×CF
= 2×3×4/2 + 2×√13×9 + 4×9
=12 + 18√13 + 36
= 48 + 18√13 cm²
A cube represents 1,000 and a flat 100. You can solve this problem by saying the number out loud. "One thousand, two hundred." That means that you need one thousand (cube) and two hundreds (flat). So one cube and two flats will be 1,000+100+100, which equals 1,200.
Answer:
in the numerator
in the denominator
Step-by-step explanation:
First fraction simplifies to:
Dividing my a fraction is the same as multiplying by the reciprocal, so the second fraction simplifies to:
So the equation becomes:
The (x+3) and (x+5) terms cancel out, so what your left with is
Expanding this term you get the answer:
in the numerator
in the denominator
The two opposite sides are equal. Therefore, AF // CE and FC // EA
Also, the corner angles should not form right angles. Shape AFCE is a rhombus, thus, similar aspects to that of a diamond, or equilateral quaddritalertial (with parallel line ofc)... I hope I answered your question. Good luck.
