Start from the right side and say
6 times 8 is 48 carry the four, 6 times 9 is 54 add your 4 you carried that gives you 58, carry your five and say 6 times one is 6 add your carried 5 and you get 1188
Answer:
Therefore,
![AB=6\ unit\\BC=6\ unit\\CD=6\ unit\\DA=6\ unit\\](https://tex.z-dn.net/?f=AB%3D6%5C%20unit%5C%5CBC%3D6%5C%20unit%5C%5CCD%3D6%5C%20unit%5C%5CDA%3D6%5C%20unit%5C%5C)
Since , ABCD has four <u> Right </u> angles and four <u> Congruent </u> sides, it is a Square
Step-by-step explanation:
The four points for the Figure are
point A( x₁ , y₁) ≡ ( 0 , 6)
point B( x₂ , y₂) ≡ (6 , 6)
point C(x₃ , y₃ ) ≡ (6 , 0)
point D(x₄ , y₄ ) ≡ (0 , 0)
∠A = ∠B = ∠C = ∠D = 90°
To Prove:
ABCD is a Square
Proof:
∠A = ∠B = ∠C = ∠D = 90° .........Given:
Now By Distance Formula we have
![l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}](https://tex.z-dn.net/?f=l%28AB%29%20%3D%20%5Csqrt%7B%28%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%20%29%7D)
Substituting we get
![l(AB) = \sqrt{(6-0)^{2}+(6-6)^{2})}=\sqrt{6^{2}}=6\ unit](https://tex.z-dn.net/?f=l%28AB%29%20%3D%20%5Csqrt%7B%286-0%29%5E%7B2%7D%2B%286-6%29%5E%7B2%7D%29%7D%3D%5Csqrt%7B6%5E%7B2%7D%7D%3D6%5C%20unit)
Similarly for BC ,CD ,DA we have
![l(BC) = \sqrt{(6-6)^{2}+(0-6)^{2})}=\sqrt{(-6)^{2}}=6\ unit](https://tex.z-dn.net/?f=l%28BC%29%20%3D%20%5Csqrt%7B%286-6%29%5E%7B2%7D%2B%280-6%29%5E%7B2%7D%29%7D%3D%5Csqrt%7B%28-6%29%5E%7B2%7D%7D%3D6%5C%20unit)
![l(CD) = \sqrt{(0-6)^{2}+(6-6)^{2})}=\sqrt{(-6)^{2}}=6\ unit](https://tex.z-dn.net/?f=l%28CD%29%20%3D%20%5Csqrt%7B%280-6%29%5E%7B2%7D%2B%286-6%29%5E%7B2%7D%29%7D%3D%5Csqrt%7B%28-6%29%5E%7B2%7D%7D%3D6%5C%20unit)
![l(DA) = \sqrt{(0-0)^{2}+(6-0)^{2})}=\sqrt{6^{2}}=6\ unit](https://tex.z-dn.net/?f=l%28DA%29%20%3D%20%5Csqrt%7B%280-0%29%5E%7B2%7D%2B%286-0%29%5E%7B2%7D%29%7D%3D%5Csqrt%7B6%5E%7B2%7D%7D%3D6%5C%20unit)
Therefore,
![AB=6\ unit\\BC=6\ unit\\CD=6\ unit\\DA=6\ unit\\](https://tex.z-dn.net/?f=AB%3D6%5C%20unit%5C%5CBC%3D6%5C%20unit%5C%5CCD%3D6%5C%20unit%5C%5CDA%3D6%5C%20unit%5C%5C)
Since , ABCD has four <u> Right </u> angles and four <u> Congruent </u> sides, it is a Square

Answer:</h3>
y = -1/2x +(4 1/2)
<h3>
Step-by-step explanation:</h3>
The two marked points (-1, 5) and (1, 4) differ in y-value by -1 and x-value by +2, so the slope is -1/2.
The y-intercept is halfway between the marked y-values, so is at 4 1/2.
Putting these numbers into the slope-intercept form of the equation for a line, ...
... y = mx + b . . . . for slope m and y-intercept b
we have ...
... y = -1/2x +(4 1/2)
