Answer:

x = 12

Step-by-step explanation:

(4x - 5)  \degree +(3x + 11) \degree  = 90\degree \\(complementary \:  \angle s)  \\  \\ (4x - 5 + 3x + 11)\degree  = 90\degree  \\  \\  (7x  + 6)\degree  = 90\degree  \\  \\ 7x + 6 = 90 \\  \\ 7x = 90 - 6 \\ 7x = 84 \\  \\ x =  \frac{84}{7}  \\  \\ x = 12

No, u cant. Because they are not like terms

2v + 4v = 6v...u can if they have exactly the same variable
3x^2 + 2x...cant
x^2 + 4x^2...can...= 5x^2
3 + 3 ....can

Can anyone please help me to find the area of this please
valentinak56 [21]

9514 1404 393

Answer:

  √35 +3√7 -6 . . . square units

Step-by-step explanation:

The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.

Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.

The overall width is the sum of the given partial widths:

  width = (√7 -2) + (2) = √7

Then the area of the bounding rectangle is ...

  A = LW = (√5 +3)(√7) = √35 +3√7

The area of the upper right empty-space is ...

  A = LW = (3)(2) = 6

Then The area of the shaded figure is ...

  √35 +3√7 -6

Answer:

rectangle

Step-by-step explanation:

Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. A regular polygon is one that has equal sides. Polygons also have diagonals, which are segments that join two vertices and are not sides.
