Answer:

Solutions are (6,3) and (-2,3).

Step-by-step explanation:

From the first equation given we can write:

$(x-2)^{2} = 16-(y-3)^{2}\\$

substituting for $(x-2)^{2}$ in the second equation given we get

$\frac{16-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} = 1$

$\frac{-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} =0$

∴ y=3

Putting y=3 in the first equation we get

$(x-2)^{2} = 16$

x-2 = ±4

Hence x=6 or x=-2.

The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 21.7 square centimeters. The

neonofarm [45]

I believe the formula to find the height would be h= 2a/b and if you use that formula and plug in the area (21.7) of each triangle as well as the base (6) then you would get a height of 7.2 cm. I hope this is correct! :)

The length of a parallelogram exceeds its breadth by 30 cm. If the perimeter of the parallelogram is 2 m 60 cm, find the length

Nuetrik [128]

$\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}$

$\longrightarrow \sf{2(1 + b) = 260}$

$\longrightarrow \sf{2(x+30+x) = 260}$

$\longrightarrow \sf{ 2x+30 = \dfrac{260}{20} }$

$\longrightarrow \sf{2x + 30 =130}$

$\longrightarrow \sf{2x = 130 - 30}$

$\longrightarrow \sf{2x = 100}$

$\longrightarrow \sf{x= \dfrac{100}{2} }$

• $\longrightarrow \sf{b= \underline{50cm}}$

$\longrightarrow \sf{= x + 30}$

$\longrightarrow \sf{= 50 + 30}$

• $\longrightarrow \sf{ \underline{80cm}}$

$\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}$

$\large\bm{Breadth= \: 50cm}$

$\large\bm{Length= \: 80cm}$
