Find the errors and correct the following mathematical sentences.​

(ii) x(3x + 2) = 3x² + 2

(iv) 2x + x + 3x = sx

(vi) 3x + 2y = 6xy

(viii) (2x)² + 5x = 4x + 5x = 9x

Corrected :-

(ii) x(3x + 2) = 3x² + 2x

(iv) 2x + x + 3x = 6x

(vi) 3x + 2y = 3x + 2y

(viii) 4x + 5x = 9x

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
