5(9)+70(6)-79+31+1-210-208=

okay so PEMDAS

P=parenthesis. There isnt anything in a parenthesis, the parenthesis here are for multiplication.

E=exponents. no exponents.

M=multiplication. we have that so do that first.

5(9) and 70(6) that equals 45 and 420. now the equation is

45 + 420 - 79 + 31 + 1 - 210 - 208

D=Division. no division

A=Addition

S=subtraction. there is both. go left to right.

45 + 420 =465. now the equation is 465 - 79 + 31 + 1 - 210 - 208

465 - 79 = 386. now the equation is 386 + 31 + 1 - 210 - 208

386 + 31 = 417. now the equation is 417 + 1 - 210 - 208

417 + 1 = 418. now the equation is 418 - 210 - 208

418 - 210 = 208. now the equation is 208 - 208

208 - 208 = 0. Therefore 5(9) + 70(6) - 79 + 31 + 1 - 210 - 208 = 0

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
