Answer:
2a...true
2b...false
2c....false
2d....false because you are supposed to add and not multiply
The answer to your question is 8, because you replace z with 2
Answer:
r=4
Step-by-step explanation:
15r-6r=36
9r=36
r=36/9
r=4
Answer:
The answer is B
Step-by-step explanation:
plug 2 into x to see
A.
x^2 + 8
2^2 + 8
4 + 8 = 12
B.
3x^2 + 1
3(2)^2 + 1
3(4) + 1
12 + 1 = 13
C.
2x^3 + 5
2(2)^3 + 5
2(8) + 5
16 + 5 = 21
D.
x^2 + x
2^2 + 2
4 + 2 = 6
Answer:
6x = 48, 180/z = 90, and 10y + 8 + 138 = 180
Step-by-step explanation:
48 and six x are vertical angles they form a kind of x so they are complementary or equal
180/z and the 90 degree angle are supplementary meaning they add to 180 so 90 minus 180 = 90
the same thing is true for 10y + 8 its supplementay with 138 so 10y + 8 + 138 = 180
