Answer:

6cm

Step-by-step explanation:

area =  \frac{1}{2} \times  base \times  height \\ 42 =  \frac{1}{2}  \times b \times 14 \\ 42 =  \frac{14b}{2}  \\ 42 = 7b \\  \frac{42}{7}  =  \frac{7b}{7}  \\ base = 6cm

What is the value of p if the expression 4(n+7) is equivalent to (n+p)4?
nikitadnepr [17]

Answer:

p = 7

Step-by-step explanation:

set the expressions = to each other

4(n+7) = 4(n+p)

distribute the 4 on both sides(multiplying the numbers on the inside)

4n+28 = 4n+4p

subtract the 4n from the right and left

28 = 4p

divide by 4

p = 7
