Answer:
slope of 2y- 5X = -20: m=
Convert to standard form: 5x- 2y=20
Slope using standard form: m=5/2
slope - Intercept form of 2y-5x= -20:
y=mx+b
y=5/2x-10
Axis interception points of 5/2x-10:
X Intercepts: (4, 0),
Y Intercepts: (0, - 10)
Answer:ez
Step-by-step explanation:
A cube has 6 sides.
first calculate the area of 1 side and then multiply it by 6
the area for one side = S^2 ( or SxS)
15^2 = 15 x 15 = 225 square inches
now multiply that by 6:
225 x 6 = 1350 square inches total
the answer is B.
42 - 47
Polygons are
triangle, trapezoid, triangle, parallelogram, rectangle and parallelogram
The area of triangles = 1/2 * base * haight.
Area of the parallelograms = height * base.
Area of rectangle= width * length
Area of trapezoid = 1/2 * (a + b) * height where a and b are the opposite parallel sides
The perimeters = sum of the sides of the polygons.
