What’s the ara of each figure?
Grace [21]

Answer:

433 in.²

Step-by-step explanation:

Divide the figure into 2 rectangles

Area of the figure = area of the bigger rectangle + area of smaller rectangle

✔️Area of bigger rectangle = L*W

L = 29 in.

W = 13 in.

Area of the bigger rectangle = 29*13

= 377 in.²

✔️Area of the smaller rectangle = L*W

L = 7 in.

W = 8 in.

Area of the bigger rectangle = 7*8

= 56 in.²

✅Area of the figure = 377 + 56 = 433 in.²

Which polynomial is in standard form? a)2xy^3 +3x^3 y^4 -4x^4 y^5 +9x^5 y^6 b)8x^5 -5y^4 -2xy^5 + x^2 y c)x^3 y^2 -3x^2 y-9x^4 y
Serhud [2]

Answer:

d) 5x^7 y^2 + 7x^6 y^5 -14x^3 y^7 +51x^2 y^9

Step-by-step explanation:

A polynomial is said to be in standard form if its terms are arranged in order of decreasing degree. That is the first term is of highest degree followed by the second term then the third term and so on. The terms of a standard polynomial are ordered from highest degree to lowest degree.

The polynomial 5x^7 y^2 + 7x^6 y^5 -14x^3 y^7 +51x^2 y^9 is in standard form because the degree of x are arranged from highest degree to lowest degree.

Which is the graph of the linear inequality 2x-3y < 12?
defon

Answer:

First, transform the given equation into the slope-intercept form, y = mx + b.

2x - 3y < 12

3y > 2x - 12

y > \frac{2}{3}x - 4

Since the equation is y > \frac{2}{3}x - 4, first draw the graph of y = \frac{2}{3}x - 4 with a dotted line (because it is >, not ≥) and shade the area above the dotted line.
