Explanation: find the area of one of the triangles, A=(b*h)/2, and then one of the rectangles, A=l*w. Multiply the triangles area by two, there are two triangles. Multiply the rectangles areas by three, there are three rectangles. I’ve included calculations in the picture below.
Answer:
3
Step-by-step explanation:
Each of the lines lengths multiply by 3.
Answer:
Step-by-step explanation:
we have that

Using a graph tool
see the attached figure
The function represent a vertical parabola that open up
the vertex is a minimum-------> is the point (-0.5, -9.3)
The x-intercepts are the points when the y coordinate is equal to zero
The x-intercepts are the points (-3.5, 0) and (2.5, 0)
so
the function cross the negative x-axis at point
therefore, the answer is
(-4, 0) and (-3, 0)
