Answer:
You will do the Distributive Property first.
Step-by-step explanation:
You will do the Distributive Property first.
4(x - 3) = 9 <u>distribute the 4 into the x and -3.</u>
4x - 12 = 9 <u>add -12 to both sides.</u>
4x = 21 <u>divide 4 on both sides.</u>
x = 5.25 is your answer.
Step-by-step explanation:
Volumeof cube = s³
= 5³
=125cm³
Surface area of cube = 6•s²
= 6 x 5²
= 6 x 25
= 150cm²
Answer:
Hello! answer: x = 83
Step-by-step explanation:
x = 83 because 83 + 83 + 41 + 41 + 56 + 56 = 360
Hope this helps!
Answer:
x= 8.1
Step-by-step explanation:
The given triangle is a right angle triangle.
We cannot use the Pythagoras theorem as the lengths of all sides are not known. We will use triangular ratios here to solve the given problem.
As it is clear from the diagram that x is the hypotenuse of the triangle and 11 is the length of the base. We will use a ratio in which base and hypotenuse are used.
So,
cos θ= base/hypotenuse
cos 36=x/10
0.8090=x/10
8.090=x
x=8.090
Rounding off to nearest 10
x=8.1
