Answer:
x = -2y + 12
Step-by-step explanation:
Let's solve for x.
x + 2y = 12
Step 1: Add -2y to both sides.
x + 2y + −2y = 12 + −2y
x = −2y + 12
Answer:
10.5 I think
Step-by-step explanation:
(1/2) *12 is 6
(1/2)*21 is 10.5
The area is 270 inches, because you would do length times width, which in this situation is 28 and 15. You multiply them, and you get 270.
The total surface area of the object shown in the diagram is 164 inches.
<h3>
What is the total surface area?</h3>
The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object. The object shown is the net of a cuboid.
Total surface area of a cuboid = 2 (lw + wh + lh)
where:
• l = length
• w = width
• h = height
2 { (10 x 3) + (10 x 4) + (4 x 3)}
2 (30 + 40 + 12)
2 x 82 = 164 inches
