Answer:
The first one is 648 and the second one is 11,600
Step-by-step explanation:
12x + 5 - 4x + 2x² =
= 2x² + 12x - 4x + 5 = <u>2x²</u><u> </u><u>+</u><u> </u><u>8x</u><u> </u><u>+</u><u> </u><u>5</u>
3(6-4y)-2y=1
18-12y-2y=1
18-14y=1
-14y=-17
Y=17/14
Now with a calculator plug in 17/4 multiply it by 4 and subtract the solution from 6 and h get x
Given:

To find:
The missing length marked with a question mark.
Solution:
Let x be the missing value.
We have,

Corresponding sides of similar triangles are proportional, so

Using this, we get

On substituting the values, we get


On cross multiplication, we get




Therefore, the missing length is 56 units.
