Question

Evaluate (x+4)(x+10).
Find the value of K if x=2,y=1 is a solution of the equation 2x+3y=k.​

Answer 1

Answer:

Given equation:

2x+3y=k

Now putting x=2 and y =1 in equation

⇒2(2)+3(1)=k

⇒4+3=k

⇒k=7

Answer 2

Step-by-step explanation:

(i) x²+4x+10x+40

= x²+14x +40

(ii) 2*2+3*1 = k

k = 7
