The answer is a. Tell me if im wrong
Ok first one since they have like terms in the denominator just cancel those and you will be left with x^2=9, now subtract 9 from both side to get x^2-9=0 now find the common factors.. we need to find a number that is the same and can be multiplied to get -9 and added and subtracted to eliminate it.. 3 times -3 gives you -9 and if you add or subtract them they eliminate themselves.. so our factors will be (x-3)(x+3) now set each set equal to zero to get the final answer of x. x-3=0 add 3 to both sides to get x=3 now with x+3=0 subtract 3 from both sides and you will get x=-3 so our both sets of number for x are 3,-3 so your answer for the first one is the second option.
for the second I am stuck I don't understand sorry!!!
Answer:
Step-by-step explanation:
Given
Strawberry = 6.18 pound
Raspberry = 6.1 pound
Required
Represent the given parameters with an inequality and describe the inequality
From the given parameters, we understand that the number of strawberry is more than the number of raspberry
The bold text above implies greater than;
Representing that, using mathematics notations; we have
Strawberry > Raspberry
Substitute 6.18 for Strawberry and 6.1 for Raspberry;
Hence, the inequality is:
<em>The meaning of the inequality is that Gina needs more pounds of Strawberry than Raspberry to make the jam</em>
Answer:
64.9 inches
Step-by-step explanation:
3 * 7.8 = 23.4
5 * 9.2 = 46
23.4 + 46 = 64.9 inches
Answer: First option.
Step-by-step explanation:
You know that the meaning of the symbol of the inequality "<" is: Less than.
So, you can check each option to find the number that could be a length of this piece of wood.
Given , you can substitute each number given in the options into this inequality. Then:
Therefore, a lenght of the piece of wood could be 4.5
