Answer:
6A, D
Step-by-step explanation:
So, you have A = b*h. The general formula for the area of a triangle. Then, we double the base and triple the height. We then get the expression (2b)*(3h).
Since it is multiplication, we can multiply 2 and 3 to get 6 and get 6*b*h.
Though, we know b*h is just A so we get 6A.
To find out how much money Samantha earned this week, we just need to multiply the rate of money she earns per hour by the amount of hours she worked.
9.50 * 40.5 = 384.75
Samantha earned $384.75 this week.
Hope that helped! =)
Hello - let's do this step by step. Show your work.
You're asking: 9(8−x)=3x.
Now, simplify both sides of the equation.
9(8−x)=3x
(9)(8)+(9)(−x)=3x (To do that, distribute)
72+−9x=3x
−9x+72=3x
Now, subtract 3x from both sides.
−9x+72−3x=3x−3x
Simplify,
−12x+72=0
After, subtract 72 from both sides.
−12x+72−72=0−72
−12x=−72
Last thing, divide both sides by -12.
-12x/12 = -72/-12
Divide.
Therefore, you have <u>x = 6</u> as your final answer.
Answer:
sqrt7
Step-by-step explanation:
cosA = b/3 = sqrt2 /3
so b = sqrt2
apply the pythagorean theorem
a = sqrt7
