40 times 3/3+5= Niamh’s amount = 40x3/8 = 15 pencils
40 times 5/3+5= Jack’s amount =
40x5/8 = 25 pencils
Answer: The surface area of each cube is 24 ft² (24 square feet)
Step-by-step explanation: The boxes according to the question are shaped like cubes, which means the shape we have here has square faces on all sides. Also the boxes have been opened up into nets and this shows each box as having 6 faces.
The area of each face is derived as follows;
Area = L x W
Area = 2 x 2
Area = 4 ft²
Having calculated the surface area of each face, a box or cube with 6 faces will have its surface area as;
Area of box = Face area x 6
Area of box = 4 x 6
Area of box = 24 ft²
Therefore in designing labels for all of the boxes, Raj would need 24 square feet of label for each box.
Answer:
B.
Step-by-step explanation:
Since C and A are parallel
and B is perpendicular to C
then B is also perpendicular to A
meaning they have the same angle so 90 Degrees.
-4xy^6 * -3x = 12x^2y^6
-4xy^6 * 2y = -8xy^7
6 * -3x = -18x
6 * 2y = 12y
Answer = 12x^2y^6 + -8xy^7 + -18x + 12y
