Answer:
452.16cm squared
Step-by-step explanation:
Area for a circle formula is A = pi * r^2
Area = 3.14 * 12^2
Area = 452.16
There 2 angles are corresponding angles, in which the angle measurements would have the same degree.
Set the two angles equal to each other, and solve for x.
7x - 1 = 8x - 14
Isolate the x. Subtract 8x from both sides, and add 1 to both sides
7x (-8x) - 1 (+1) = -14 (+1)
7x - 8x = -14 + 1
-x = -13
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-13)/-1
x = -13/-1
x = 13
13 is your answer for x.

Answer:
slope = 0
Step-by-step explanation:
recall that the equation of a line can be expressed as:
y = mx + b, where m is the slope and b is the y-intercept.
in our case we are given y = 3
which can be re-written:
y = (0)x + 3
if we compare this with the general equation above, we can see that
slope = m = 0
Answer:
I ain't sure but I guess it's option B .
Answer:
x = 42 - 4
x = 38
Step-by-step explanation:
Given that :
Initial number of plane models = x
Number of additional models built = 4
Total number of planes = 42
Total = initial amount + additional amount
42 = x + 4
Make x the subject
42 - 4 = x + 4 - 4
x = 42 - 4
X + 4 = 42
X = 42 - 4
X = 38
