Need help with question 4 and 5

4: A=½bh

A=½(18)(14)

A=½(252

A=125m²

126÷3= 42

42 chickens

5: A=½h(a+b)

A=½(3)(4+3)

A=½(3)(7)

A=½(21)

A=10.5m²

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
