Answer:
square root of 25, 2.51, 5/2, 0.25, 10^-1, -2.5%
Step-by-step explanation:
when in the same form they are
5, 2.51, 2.5, .025, 0.1, -0.025
18x + 20 + x = 10x -3
Combine like terms
19x + 20 = 10x -3
Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:
19x = 10x -23
Subtract 10x
9x = -23
Divide 9 to isolate x:
x = -23/9
Simplify to get a mixed number:
x = -2 5/9
The surface area of the two triangles is 12 cm^2.
3*4=12
The surface area of the bottom rectangle is 8 cm^2.
4*2=8
The surface area of the rectangle that is on the left side of the figure is 6 cm^2.
3*2=6
The surface area of the rectangle that is on the top side of the figure is 10 cm^2.
To find the third side of the triangle, use the Pythagorean theorem.
3^2+4^2=h^2
9+16=25
The third side of the triangle is 5 cm.
The surface area of the whole figure is 36 cm^2.
12+8+6+10=36
Answer:
D. -3 + 6
Step-by-step explanation:
Starting from zero, we move 3 units to the left. This gives -3.
We now change direction and move to the right 6 units. This gives +6.
Putting the two movements together gives
The correct choice is D.
Note that moving to the left is considered to be negative while moving to the right is considered positive.
