La fachada de un edificio tiene forma de rectángulo, de altura 18,5 m y de anchura 9 m, se quiere pintar costando 29,45 euros el m2. Se ha de tener en cuenta que hay 16 ventanas de 1,4 m por 1.15 m. ¿Cuál es la superficie total que hay que pintar? ¿Cuánto costará?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

the answer is a.
