Well first divide 12×85=___ ÷340
Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
(x + 1)² = x² +2*x*1 + 1² = x² + 2x + 1
y = 4(x+1)² - 4
y = 4(x² + 2x + 1) - 4
y = 4*x² + 4*2x + 4*1 -4
y = 4x² + 8x + 4 - 4
y = 4x² + 8x
Answer:
13.75
Step-by-step explanation:
1.25x9=11.25
25-11.25=13.75
It is better to illustrate the problem. As you can see on the figure, angle A and angle C are opposite angles. First, we define parallelogram. Parallelogram is a quadrilateral with two sets of parallel sides. Moreover, the opposite sides and the opposite angles are equal.
From the definition alone, there is no need to solve. Angle C = Angle A =
55 °.
BC² = 11² + 11²
BC² = 121 + 121
BC² = 242
BC = √242
BC = 11√2
Answer: 11√2
