Let us consider the values of x and y
So 3x-2y-5=17
=>3x-2y=22.......(1)

Putting it in the first eq.

3x-2y+9= 22+9=31(Ans)
(Because 3x-2y=22 in equation 1)


Now multiplying (1) by 3

(3x-2y)*3=(22*3)

9x-6y=22*3

9x-6y=66(Ans)

I hope it helps and you understand.

Write in standard form (×+4)(×-5)=4 find the value of a,b,c​
Alex17521 [72]

Answer:

x^{2} - x - 24 = 0

a = 1

b = 1

c = -24

Step-by-step explanation:

(x + 4)(x - 5) = 4

x(x - 5) = x^{2} - 5x

4(x - 5) = 4x - 20

x^{2} - 5x + 4x - 20 = 4

x^{2} - x - 20 = 4

x^{2} - x - 20 - 4 = 0

x^{2} - x - 24 = 0

a = 1

b = 1

c = -24

Please help me on this!!​

Answer:

TW = ST

Step-by-step explanation:

RS = RW (Given)

RT = RT (reflexive property)

This makes ∆RST congruent to ∆RWT based on the reflexive property of congruence.

Therefore, the third corresponding sides, TW and ST would be congruent to each other.

Thus:

TW = ST
