Answer:
44 units²
Step-by-step explanation:
For triangles: (bases and heights of both triangles are equal)
Base = 4 units, height = 3 units
For trapezoid:
Base 1 = 5 units, base 2 = 3 units, height = 8 units
Area of figure = Area of two triangles + Area of trapezoid
= 2 *1/2 * base * height + 1/2(base 1+ base 2) *height
=4*3 + 1/2(5+3)*8
= 12 + 8*4
= 12 + 32
= 44 units²
324mm = 324 ÷ 10 = 32.4cm
Answer:
<h3>
-58, -57, -56</h3>
Step-by-step explanation:
x - the first of consecutive integers
x+1 - the second of consecutive integers
x+2 - the third of consecutive integers
x+x+2 - sum of the first and third integers
3(x+x+2) - three times the sum of the first and third integers
3(x+x+2) = -342
÷3 ÷3
2x + 2 = -114
-2 -2
2x = -116
÷2 ÷2
x = -58
x+1 = -58 + 1 = -57
x+2 = -58 + 2 = -56
