Answer:
7^2 =49
Step-by-step explanation:
Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!
Make a game out of it. it says that softball dimond is 50% bigger than a basball feild. also with the balls. transfer the feet to cm and go from there. i think you need to transfer the percentage into cm as well to get the answer.

Answer:
If b=-3 then the first expression is equal to 24 and the second expression is equal to -14.
If b=-2 then the first expression is equal to 8 and the second expression is equal to -36.
If b=10 then the first expression is equal to 440 and the second expression is equal to 324.
Yes, it is true.
Step-by-step explanation:
b=-3:
4b(b+1)=4(-3)(-3+1)=-12(-2)=24
(2b+7)(2b-8)=(2(-3)+7)(2(-3)-8)=(-6+7)(-6-8)=1(-14)=-14
b=-2:
4b(b+1)=4(-2)(-2+1)=-8(-1)=8
(2b+7)(2b-8)=(2(-2)+7)(2(-2)-8)=(-4+7)(-4-8)=3(-12)=-36
b=10:
4b(b+1)=4(10)(10+1)=40(11)=440
(2b+7)(2b-8)=(2(10)+7)(2(10)-8)=(20+7)(20-8)=27(12)=324
