The following steps are used to rewrite the polynomial expression (x+4y+z)(x-7y). Step 1: x(x-7y)+z(x-7y)
Step 2: x^2-7xy+4yx-28y^2+zx-7zy
Step 3: x^2-7xy+4xy-28y^2+xz-7yz
Step 4: x^2-3xy-28y^2+xz-7yz

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

make sure you have version 2.50

try looking in the very back of the book : )
