2x + 40
Divide both sides by 2
You get x + 20
Answer:
-1
Step-by-step explanation:
-9a<u>(-16+3)</u>=4a ; solve for whole numbers first.
-9a-(13)=4a ; A negative 16 plus a positive 3 is 13.
-9a-4a=13 ; Switch 13 and 4a to make it easier to solve.
-13a=13 ; Now divide each side by -13.
a=-1
Answer:
<em>B.) ABC is similar to DEF because 6/4 = 12/8 = 9/6!</em>
Step-by-step explanation:
ABC is similar to DEF because the ratio of there sides are the same! If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

The ratio stays 1.5 in all instances! These tringles are similar.

I think it is b not 100% tho
A and D can be automatically eliminated since the a side cannot be longer than the hypotenuse in a triangle.
Recognize that the two triangles are similar triangles, you get
2.7/3.6 = h/1.5 => h = 1.125.
