Question

V = 5x + 2y

x= 3
y=-4
a) Work out the value of V
b) Expand 3p(p + 5)
c) Solve 4(k - 6) = 20

Answer 1

a.7

b.

`3 {p }^(2) + 15p`

c.k=11

Explanation:

a.V=5x + 2y ,x=3,y= -4

V=5(3)+2(-4)

=15+(-8)

=15-8

=7

b.3p(p + 5)

=

`3 {p}^(2) + 15p`

c.4(k-6)=20

4k-24=20

4k-24+24=20+24

4k=44

4k/4=44/4

k=11

hope it's helpful ❤❤❤❤

THANK YOU.
