To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Identities have <em>INFINITE </em>solutions.
Hope I could help! :)
This is 7 tenths, which means the fraction would be 7/10.
Answer:
15 ft
Step-by-step explanation:
12^2 + 9^2 = c^2
144 + 81 = c^2
225 = c^2
c = 15
Answer:
answer : A
Step-by-step explanation:
hello :
x² + y² + 6x + 4y + 10 = 1
(x² + 6x )+(y²+ 4y) + 10 = 1
(x² + 6x+9-9 )+(y²+ 4y+4-4) + 10 = 1
(x² + 6x+9)-9 +(y²+ 4y+4)-4 + 10 = 1
(x+3)²+(y+2)² = 4 answer : A
