1. which property justifies this statement? if x = −2, then 5x = −10. a. symmetric property of equality b. multiplication property of equality c. subtraction property of equality d. transitive property of equality 2. drag a statement or reason to each box to complete the proof. if 3(x−4)=x+4, then x=8. statement: reason: 1. 3(x−4)=x+4 > given 2. 3x−12=x+4 > 3. 3x−12+12=x+4+12 >4. 3x=x+16 > simplifying 5. 3x−x=x+16−x > 6. 2x=16 > simplifying 7. 2x2=162 > 8. x=8 > simplifying a. subtraction property of equality b. distributive property c. addition property of equality d. division property of equality

This is irrelevant, but was THAT many exclamation points necessary?

Anyway, these aren't that hard, you gotta just use your brain a bit. These problems use a bit of simple common sense if you put 2-and-2 together and look into it. Look for signs and just use your head, it's hard to explain but just try. ^^

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
