please help me I will mark you brilliant if you answer my question
thank you​

Answer 1

Answer:

i) 3y² + 5y-4 - 8y +y² +4

= 4y² -3y

ii) 2x² + x - a = 5 ------- x = 0

2(0) + 0 - a = 5

a = -5

iii)

$\frac{ {12}^{4} \times {9}^{3} \times 4 }{ {6}^{2} \times {8}^{2} \times 27}$

$= 162$

iv) scalene triangle

parallelogram

trapezium

v) 2a - 2b - 4 - 5 + a

= 2(-1) - 2(-2) - 4 - 5 - 1

= -2 + 4 - 4 - 6

= -8

vi)

$\frac{ {5}^{2} \times 25 \times {t}^{8} }{ {10}^{3} \times {t}^{4} }$

$= 625 \times {t}^{4} = 1000$

${t}^{4 } = 1.6$

vii)

5m+7 = 17

5m = 10

m = 2

viii)

10p + 10 = 100

10p= 90

p = 9
