Answer:
It's C.
Step-by-step explanation:
x + y + x + y + 3(y + 5)
= x + y + x + y + 3y + 15
= 2x + 5y + 15.
Answer:
D 97 cm^2
Step-by-step explanation:
The area of the circle is
A = pi * r^2
We need to convert diameter to r
d =2r
d/2 =r
12/2=r
6 =6
The radius is 6
A= pi *6^2
A = 36 *(3.14)
A = 113.04 cm^2
Now the fraction of the circle that is shaded is 301degrees out of 360
(A circle is 360 degrees)
310/360 * area of a circle
310/360 * 113.04
97.34
Answer:
x = -1 or x = -3
Step-by-step explanation:
x + 3/x = -4
x² + 3 = -4x
x² + 4x + 3 = 0
(x + 1) (x + 3) = 0
x = -1 or x = -3
check: (-1) + (3/-1) = -1 - 3 = -4
(-3) + (3/(-3)) = -3 -1 = 14
Suppose U={0, 1, 2, 3, 4, 5, 6}, A={2, 4, 6}, and B={1, 2, 3}. Tell whether each statement is true or false.
mina [271]
That asks if A is a subset of U. Since each member of A, namely 2, 4 and 6, is also in U, A is indeed a subset of U.
Answer: TRUE
