7^2 - 3(4-2)^0 - 2(7+3) + 3^2
= 49 - 3 - 20 + 9
= 35
hope it helps
P.S
any number to the 0 power is always equal 1
A) 62 -2t < 40 . . . . . t is time in hours
c) 6+3n ≤ 96 . . . . . . n represents the number
e) 4 +2W < 62 . . . . . . W represents the width of the rectangle
f) 3.50 +0.15p ≤ 5.00 . . . . . p is the number of pencils Miranda buys
we know that
If lines m and n are parallel
then
m<1 and m<5 are corresponding angles
so
m<5=m<1
therefore
m<5=135 degrees
