Answer:
Surface area of cube = 6x²
surface area of cube = surface area of sphere
it means that 6x²=4πr²
x²=
The value of x is 5. Angle one and four are vertical. You can do this by writing 7x = 3x + 20. Isolate the variable by moving 3x to the other side. If you do this, 3x becomes negative, and you end up with 7x-3x = 20 --> 4x = 20.
x=5.
Answer:
92.8 km
Step-by-step explanation:
s=d/t
58=d/1.6
58*1.6=d
92.8=d
(x-3)^2 x=a number in this case
Answer:
C, E, F
Step-by-step explanation:
A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.
B is a true statement.
C is true because when angles undergo dilations, their "size" does not change.
D is false because dilations do not increase the measures of angles.
E is false because a triangle that underwent a dilation becomes similar, not congruent.
F is true because of E's reasoning.
