Answer:
maybe rhombus
Step-by-step explanation:
don't take my word for it
The answer is
The diameter is 4 (2) = 8 and height is 10(2) = 20
For the sides, use area of a cylinder = ph
p = 8 pi cm, ht = 20 cm. A = 160 pi sq cm
Base are 2 circles, each with radius 4 pi
Area = pi r^2 = 16 pi (times 2 circles) = 32 pi sq cm
Kim drives = x
Terry drives = 2x
Jerry drives = 6x
Let us go through our answer choices and choose one.
A is incorrect because we are not being asked to add anything.
B is incorrect because it equals what all of the drivers drive.
2(x+3)
2*x + 2*3
2x + 6x
C is incorrect because we are not being asked to subtract.
D is correct because Jerry drives 3 times as much as terry.
2x*3
6x
So our final answer is D. 6x
Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
