It's already expanded but it looks like this when simplified you can distribute so x squared + 8x
Answer:
Step-by-step explanation:
Find the total surface area of the
following square pyramid:
6 cm
8 cm
SA = [?] cm2
Given:
Budget = $30
cost of pizza = $9
cost of drinks = $1
number of pizza = p
number of drinks = d
pizza and drinks should only be equal to or less than the budget of $30.
$9p + $1d <u>< </u>$30
unit cost of pizza : 9
unit cost of drinks : 1
total cost of set (p & d) 10
pizza = 9/10 x 30 = 27 total cost of pizza
drinks =1/10 x 30 = 3 total cost of drinks
27 ÷ 9 = 3 number of pizzas to order
3 ÷ 1 = 3 number of drinks to order
To check:
9p + 1d <u>< </u>30
9(3) + 1(3) <u>< </u>30
27 + 3 <u>< </u>30
30 <u>< </u>30
no. of right answers = 60
no. of wrong answers = 40
63 x .04 = 2.52
That is your answer to the question! Hope I helped :)
