Answer:
2x − 5x + 11
Step-by-step explanation:
1) -2.3(x-1.2)=-9.66
2) x-1.2=-9.66+2.3
3) x=-9.66+2.3+1.2
4) x=-7.36+1.2
5) x=-6.16
Do a proportion
10/75= 1/x
Cross multiply and divide
75 x 1= 75
75 divided by 10 is 7.5

Step-by-step explanation:
0.37 + 0.23 x 3 or 0.37 + 0.23 + 0.23 + 0.23
Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches
area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches
