The area of square abcd is 7 cm^2
show that x^2+4x=3

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

you already gave the answer

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
