Question

1. Solve the equation : 8x + 4 = 3(x - 1) + 2.
2. The measure of four angles of a quadrilateral are 3x, 4x, 5x and 6x. Find all the angles.
3. Construct a square PQRS, given that PQ = 5 cm.
4. Find square root : 6084
5. Find cube root : 5832​

Answer 1

Answer:

1.8x + 4 = 3x - 3 + 7

Transposing 3x to L.H.S and 4 to R.H.S,

we obtain

8x - 3x = - 3 +7 - 4

5x = - 7+7

X = 0

L.H.S = 8x + 4 = 8 x (0) + 4 = 4

R.H.S = 3(x - 1) + 7 = 3 (0 - 1) + 7 = - 3 =

+ 7 = 4

L.H.S. = R.H.S.

Hence, the result obtained above is
