Answer:
D) -6
Step-by-step explanation:
• solve x + 56+40= 90 90 because the triangle is a 90 degrees angle
• x+96=90
-96. -96
x=-6
1.1x+1.2x-5.4=-10
11/10x+12/10x-54/10=10
11x/2.5+2^2-1*3/5x-3^3/5=-10
(11x)+2(2*3x)+2(-3^3)/2*5=-10
11x+2(6x)+2(-27)/2*5=-10
11x+2*6x-2*27/2*5=-10
11x+12x-54/2*5=-10
23x-54/2*5=-10
23x-54=-100
23x=-46
23x/23=-46/23
x=-2*23/23
x=-2

Step-by-step explanation:
we know that
To find the dimensions of the enlarged poster, multiply the original dimensions of the poster by the scale factor
so
![18(\frac{7}{2})=63\ in](https://tex.z-dn.net/?f=18%28%5Cfrac%7B7%7D%7B2%7D%29%3D63%5C%20in)
![6(\frac{7}{2})=21\ in](https://tex.z-dn.net/?f=6%28%5Cfrac%7B7%7D%7B2%7D%29%3D21%5C%20in)
therefore
The dimensions of the enlarged poster are
