Answer:
v=18
Step-by-step explanation:
26=8+v
<em>Swap sides:</em>
8+v=26
<em>Subtract 8 from both sides:</em>
8+v-8=26-8
<em>Group like terms:</em>
v+8-8=26-8
<em>Simplify the arithmetic:</em>
v=26-8
v=18
Can't see the figure, but the basic way to solve this problem is to use the formula for volume of a pyramid which is (length * width * height )/3. Slant height is just the square root of ((length/2)2 + height2) recognizing that there is a right triangle there. Since slant height increased by 4 cm when its height increased by 2cm, you know that the length/2 term had to increase by the square root of 12 (22+root(12)2) = 42=16. From there you can figure out the rest pretty readily.
Answer:
40
Step-by-step explanation:
angle CHA is equal to angle HGB because they are alternate interior angles.
This means that angles CHA and AGH are supplementary, add up to 180 degrees.
So, 5x + x + 12 =180
6x = 168
x = 28
<CHG = x + 12 = 28 + 12 = 40
Answer:
6.67 m/s
Step-by-step explanation:
Answer:
-5x +2
Step-by-step explanation:
Just combine like terms and solve.
-2x^2+-6x - (x+1)(x-2)
Use foil on the second part
-2x^2-6x - x^2-x-2
Now combine like terms and you’d get your final answer
