U^2(2u+3)+7(2u+3)
(u^2+7)(2u+3)
Use the equation
A= 2(wl +hl +hw)
Where
w is width
h is height
l is length
40 times 3/3+5= Niamh’s amount = 40x3/8 = 15 pencils
40 times 5/3+5= Jack’s amount =
40x5/8 = 25 pencils
I don’t think that’s right.
This is all middle school stuff.
First do the powers. 3 power plus -5 power equals to -2 power.
2 x 5 is 10. So, it's 10 to the power of -2.
