Question

Calcule
A) 10(4p+5p)
B) 7x (x-5)
C) (x²-y)x
D) -3t (-2t-4)

Answer 1

A)10(9P)=90P
B)7X²-35
7X²=35
X²=35/7
X²=5
X=√5
C)X³-XY

D)6T²+12T

Answer 2

Olá!!!

Resoluçao!!,

a)

= 10 ( 4p + 5p )
= 40p + 50p
= 90p

b)

= 7x ( x - 5 )
= 7x² - 35x

c)

= ( x² - y ) x
= x³ - xy

d)

= - 3t ( - 2t - 4 )
= 6t² + 12t

Espero ter ajudado!!!
