7x-4=5x+15
-5x on both sides
2x-4=15
add four to both sides
2x=19
divide both sides by 2 to isolate x
x=9.5

Step-by-step explanation:

(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)

-4c² + 7cd + 8d - 3d + 8c² + 4cd (opening bracket)

PLZZZZ HELP <br> A. 178.3<br> B. 196.5 <br> C. 250.8<br> D. 292.5<br> E. 297. 1
stepladder [879]

Answer:

E, 297.1

Step-by-step explanation:

First, find the area of the triangle using the formula a= (bh) / 2

Base x height would be 16 x 12, which is 192

192 / 2 is 96 sq meters

Then, find the area of the circle using the formula a= Pi (r^2)

If the diameter is 16, the radius would be 8 because you divide by 2

8^2 is 64, 64 times Pi is approximately 201.1

Finally, add the areas together, 96 + 201.1 is 297.1 or E
