Step-by-step explanation:
100 sq ft=1200
1109sq ft=?
1109*1200/100=13308
Answer:
20 x 1 / 18= 1.11
Step-by-step explanation:
2x^2+2x-4=2(2x^2+2x-4)/2=[2(2x^2)+2(2x)-2(4)]/2=[2^2x^2+2(2x)-8]/2
2x^2+2x-4=[(2x)^2+2(2x)-8]/2=(2x+4)(2x-2)/2=2(2x/2+4/2)2(2x/2-2/2)/2
2x^2+2x-4=2(x+2)(x-1)
Answer: Option B. 2(x+2)(x-1)
Answer:
110°
Step-by-step explanation:
This quadrilateral have the same size in AD and CD, and BA and CA, so it means that, if you cut this figure in the middle (from B to D), the two triangles will be identical, and the sum of the internal angles of a triangle is 180°, so:
(110°÷2) + (30°÷2) + <C = 180°
55° + 15° + <C = 180°
70° +<C = 180°
<C = 180° - 70°
<C = 110°
And you can test it making the sum of the internal angles of the quadrilateral. The sum of the internal angles of a quadrilateral is 360°, and the angles A and C have the same measure because AD=CD and AB=BC, so:
<A + <B + <C + <D
110° + 110° + 110° + 30° = 360°
Answer:
E
Step-by-step explanation:
E is the only option where the answer would be a non--repeating answer, which is pretty much the definition of a rational number.
