The inequality should be 4x + 6 > 30
4 times x is 4x, and if anything is greater then smth, you should use > if that number is on the left.
to solve, just do what u would do in algebra, except charging the = into >
4x + 6 > 30
4x > 30 - 6
x > 24/4
x > 6

Answer:  <span> x  >  6</span>  .
_________________________
Explanation:
_________________________

4x + 6 <span> > 30 ;  Solve for "x" ; 
_________________________

Subtract "6" from both sides of the inequality:
____________________________________
4x + 6 </span>− 6 > 30 − 6 ;  to get:
____________________________________
       4x  > 24 ;
____________________________________
Divide EACH SIDE of the inequality by "4" ; to isolate "x" on one side of the inequality; and to solve the inequality (for "x") ; 
__________________________________
        4x / 4 > 24 / 4 ;  to get:
__________________________________
            x  >  6  .

Find the surface area of composite figure. Please help
Ivan

Answer:

The surface area of the composite figure is 410\ m^{2}

Step-by-step explanation:

we know that

The surface area of the composite figure is equal to the surface area of the rectangular prism of the bottom plus the lateral area o the rectangular prism of the top

so

Step 1

Find the surface area of the rectangular prism of the bottom

The surface area is equal to

SA=2B+Ph

Find the area of the base B

B=10*10=100\ m^{2}

P=4*10=40\ m

h=3\ m

substitute

SA=2(100)+40(3)=320\ m^{2}

Step 2

Find the lateral area of the rectangular prism of the top

The lateral area is equal to

LA=Ph

P=2*(4+5)=18\ m

h=5\ m

substitute

LA=18(5)=90\ m^{2}

Step 3

Find the surface area of the composite figure

320\ m^{2}+90\ m^{2}=410\ m^{2}
