(2x+1) (x+7)
I solved it by using the FOIL method, but you get the same answer either way
Answer:
B
Step-by-step explanation:
this question is not about addition and inequality, i've done elementary work that is as easy as this
Answer:20h + 21 is the only one equivalent to 4(5h + 4) + 5
Step-by-step explanation:
For the first question, the total is 240 so that goes in front of the equals sign. he has already worked 97 hours, so the expression on the right begins with 97 and adds the unknown number of hours, <em>h</em>, to it:
240 = 97 + <em /><em>h</em>
For the second question, there is no graph so I cannot answer it.
3rd question: no image, can't answer.
4th question:
Use a factor tree:
240
/ \
10*24
/\ /\
5*2 *8*3
/ / /\ \
5 * 2 *4*2 *3
/ / /\ \ \
5 * 2 *2*2 * 2 * 3
Starting with the smallest factor and using exponents we have
