Answer

7,0

Step-by-step explanation:

Substitute -6y+7 into problem one where the x is

distribute the 2 and subtract the 9 y and you will get

-21y+14=14

subtract 14 from both sides and it will be -21y=0 so y will be 0

substitute the 0 into equation 2 and find x=7

1.) 2(-6y+7)-9y=14
2.) -12y+14-9y= 14
3.) -21y + 14 = 14
4.) -21y = 0
5.) -21y/-21 = 0/-21
y = 0
6.) 2x-9(0) =14
7.) 2x=14
8.) 2x/2 = 14/2
x=7
so, your answer is (7,0)

Answer:

4√3 cm^2

Step-by-step explanation:

30 60 90 right triangle

The ratio of short leg : long leg : hypo. = x : x√3 :2x

Given Hypo BC = 4 = 2 * 2

so Long leg = 2√3

Area of ABC = 1/2 (b)(h)

= 1/2 (4)(2√3)

= 4√3

Answer

4√3 cm^2

Perimeter = 3 x 4 = 12 cm (you asked from other, so I answered for you as well)
