The value of the expression is 4.

We can find this by taking the original equation and plugging in 3 every time we see an x.

$\frac{17 + x}{x + 2}$

$\frac{17 + 3}{3 + 2}$

$\frac{20}{5}$

Length 21cm area 315cm2 find the breath

Ronch [10]

Answer:

Breadth = 15 cm

Step-by-step explanation:

Area = length x breadth

315 = 21 x breadth

$\frac{315}{21} = \frac{21}{21} \times breadth$ [ dividing both sides by 21 ]

$15 = 1 \times breadth\\\\breadth = 15 \ cm$

(b)<br> Using the formula 2T = M + 3K, find the value of K when T = 11 and M = 4.

Sunny_sXe [5.5K]

Answer:

K = 6

Step-by-step explanation:

Plug in what the letter equals to

Equation will look like:

2(11) = 4 + 3k or 3k + 4 = 2(11)

multiple the 2 by 11 and get 22

3k + 4 = 22 subtract the 4 so it can leave the 3k alone

22 - 4 = 18 now divide 3 from k and do it in the other side

18/3 = 6

so K = 6
