Question

PLS HELP ME,I'LL MARK U AS BRAINLIEST IF U HELP ME!!!! 1. Write the algebraic expressions of the following. a) Twice of a number added to 5 b) difference of the squares of two numbers m and n multiplied by 6 c) r cubed minus y squared d) five times x raised to the power of 5 added to twice of y cubed

Answer 1

Step-by-step explanation:

Let the number be x

(a) 2x + 5

(b) (m²-n²) × 6

(c) r³-y²

(d)

$5 {x}^{5} + 2 {y}^{2}$

Answer 2

Step-by-step explanation:

a)

Twice of a number added to 5.

Let the number be n.

Twice of the number: 2n

Twice of the number added to 5: $2n+5$

b)

Difference of squares of m and n multiplied by 6.

Difference of squares: $m^{2} -n^{2}$

Difference of squares multiplied by 6: $6(m^{2} -n^{2} )$

c)

r cubed minus y squared

r cubed: $r^{3}$

y squared: $y^{2}$

r cubed minus y squared: $r^{3} -y^{2}$

d)

Five times of x raised to the power of 5 added to twice of y cubed

Five times of x raised to the power of 5: $5x^{5}$

Twice of y cubed: $2y^{3}$

Five times of x raised to the power of 5 added to twice of y cubed:

$5x^{5} +2y^{3}$
