Where is the question so I can help
Answer:
60 cm
Step-by-step explanation:
perimeter of big rectangle- 13+13+25+25=76cm
perimeter of smaller rectangle- need to find the width so do 14.6+8.7=23.3
25-23.3=1.7
width of smaller rectangle=1.7
perimeter of smaller rectangle= 1.7+1.7+6.3+6.3=16
Perimeter of the shape= 76-16=60 cm
<span>Solve the following system of equations by linear combination:
3x + 2y = 7
y = x – 4
</span><span>3x+2(x-4)=7 now solve for x
3x+2x-8=7
combine terms
5x-8=7
add 8
5x=15
divide by 5
x=3
plug that into the second equation
y=3-4
y=-1
solution

Answer:
You will need 1400 cm² of paper
Step-by-step explanation:
When you wrap a gift, you wrap around the entire object. We need to find the total surface area of the prism. A rectangular prism has two rectangular faces on the end. The area of one of those faces is Height (of the prism) times Width.
Rectangular prisms also have 4 sides which are composed of rectangles. The area of one of those rectangles is length (of the prism) by the width.
Now we just need to sum up all of those areas.
