add them (1/2)ab+(1/2)c^2+(1/2)ab= ab+(1/2)c^2 ab+(1/2)(a^2+b^2) not sure which option to pick there are different preferences on what counts as 'simplified'
4. find area area=LW area=105*45=4725 depends on the area of the signs answer is 4725/(areaof1sign) anyway, round down your answer because you will have an incomplete sign if you don't
5. area=pir^2 1/2 of it is area=1/2pir^2 area=(1/4)^2pir^2 area=pi((1/4)r)^2 the radius is now 1/4 of what it was originally, meaning that the diameter is also 1/4 of what it is now we need to know diamater answer is 1/4 of current diameter
3. unclear
4. area of 1 sign not given, answer is 4725/(areaof1sign), rounded DOWN to nearest integer
5. (404 error, diameter not found) answer is 1/4 of current diameter
1)12 ÷ 3 = 4. 2) 4×2= 8. 3) 9× 8= 72. 4) 8² = 64 5) 64+ 72 = 136 6) 136 - 7 = 129. If you just want to simplify the expression you get: 8² + 9(8) - 7 But when you simplify that you get the answer below. ANSWER: 129
