Answer:
x = 4
Step-by-step explanation:
plug 3x+2 = 5x-6 cause their the same length
solve for x
subtract 3x by both sides --> 2 = 2x -6
add 6 to both sides --> 8 = 2x
now divide by 2 to get x alone --> X = 8/2

Answer:
3. 294 m²
4. 185,856 mm²
Step-by-step explanation:
To find the surface area of any figure, you can simply find the sum of the areas of all the sides. In question 3, the figure is a triangular prism that has two triangular bases and three rectangular sides. The measurements for the triangles are b = 9m and h = 6m. The formula for the area of a triangle is base times height divided by 2, or 9 x 6 = 54/2 = 27 m². However, since there are two triangular bases, the area for both is 54 m². The measurements for the other three rectangles are given:
7(10) + 8(10) + 9(10) = 240 m² + 54 m² = 294 m²
The surface area of a cube is much easier since all sides are equal and can be found using the formula:
SA = 6s², where 's' represents the measure of a side.
SA = 6(176)² = 185,856 mm²
Answer:
y = (⅖)x - 5
Step-by-step explanation:
Slope: (-3+5)/(5-0) = 2/5
(0,-5) means c is -5
y = (⅖)x - 5
