Answer:m =-1
Step-by-step explanation:
To solve m=-(4+m)+2
Open the brackets
m=-4-m+2
Collect like terms
m+m=-4+2
2m=-2
Divide through by -2
m=-1
Sorry I am not good at math either
The 3 inside angles of a triangle equal 180.
Add the 3 angles together to equal 180:
X + (5x-20) + 4x = 180
Simplify the left side by adding like terms:
10x-20 = 180
Add 20 to each side:
10x = 200
Divide both sides by 10:
x = 20
Angle A = x = 20
Angle B = 4X = 4(20) = 80
Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
Answer:
<h2>The dimensions are 3, 4 and 6 centimeters.</h2>
Step-by-step explanation:
Notice that the surface of 24 square centimeters is formed by 6 times 4, which gives 24 square centimeters.
The 12 square centimeres surface is formed by 3 times 4, which gives 12.
The 18 square centimeters surface is formed by 3 times 6, which gives 18.
Therefore, the three dimensiosn to form the prism are 3 cm x 4 cm x 6 cm.
Where 6 cm is the height, 3 cm and 4 cm are the width and length.
