Answer:
7.
8.
Step-by-step explanation:
Given:
Three sides of the triangles are given.
For Question 7
1/2 _ 1/3 _1/5
For Question 8
0.1 _ 0.15 _ 0.2
We need to use >, <, and + signs to write inequalities for the relationships among the sides of the triangles.
Solution:
Part 7.
Property of the triangles.
Sum of two side of triangles must be greater than third side.
So, first, second and third side of the triangle is
So, its satisfy the triangle rule.
Therefore, Inequality is
Part 8.
Property of the triangles.
Sum of two side of triangles must be greater than third side.
So, first, second and third side of the triangle is
So, its satisfy the triangle rule.
Therefore, Inequality is
{ y=2x+2
{ y=4x-2
2x+2=4x-2
x=2
y=2 ⋅ 2+2
y=6
(x,y)=(2,6)
——
Check solution:
{ 6=2 ⋅ 2+2
{ 6=4 ⋅ 2-2
{6=6
{6=6

Answer A. 15 glad to help
To find the surface area of the rectangular prism, use the formula:
A=2(wl+hl+hw)
Note that: w = 4, l = 12, h = 3
plug into the equation
A = 2((4)(12) + (3)(12) + (3)(4))
Simplify
A = 2(48 + 36 + 12)
A = 2(96)
Multiply
A = 96 x 2
A = 192
192 m³ is the surface area of the rectangular prism.
hope this helps
