Answer:
980
Step-by-step explanation:
Multiply the number of pens in a box by the number of boxes.
Perimeter of 30 and why 30 is because if you add it you get that and if thats wrong mutipy 11x7x6x6 to find your answer
X: -4, -2
Y: 2, 3
When you plug -4 and 2 it looks somewhat like this, 4(2)-2(-4)= 8+8+16. Then -2 and 3 would look something like this, 4(3)-2(-2)= 12+4=16.
Answer: 26
Step-by-step explanation: In this problem we have 3 consecutive even numbers whose sum is 84 and it asks us to find the smallest number.
Consecutive even numbers can be represented as x, x + 2, and x + 4.
Since the sum of these is 84, our equation reads
x + (x + 2) + (x + 4) = 84.
Simplifying on the left we get 3x + 6 = 84.
Subtract 6 from both sides and we have 3x = 78.
Divide both sides by 3 and x = 26.
So our smallest number is 26.
As there are two pairs of equal parallel sides, a rectangle has 2 lines of symmetry.
