A=area
b₁=base 1
b₂=base 2
h=heigth

A=(1/2)h(b₁+b₂)
79.2=(1/2)h(4.2+9)
79.2=(1/2) h (13.2)
h=(79.2 * 2) / (13.2)=158.4 / 13.2=12

Answer: height=12

I need help plzzzzzz

My name is Ann [436]

(1) The train travels 4 miles per gallon.

(2) The slope of the graph is $m=\frac{1}{4}$

Explanation:

(1) The miles that train travels per gallon is given by

$Miles= \frac{800}{200}$

Dividing, we have,

$Miles= 4$

Thus, the train travels 4 miles per gallon.

(2) To determine the slope, let us consider two points from the graph.

The coordinates are $(0,0)$ and $(800,200)$

Thus, substituting the coordinates in the slope formula, we get,

$m=\frac{200-0}{800-0}$

Simplifying, we have,

$m=\frac{200}{800} =\frac{1}{4}$

Thus, the slope of the graph is $m=\frac{1}{4}$

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?

Lera25 [3.4K]

Answer:

The first option

Step-by-step explaination:

$9 {xy}^{3} - 4 {y}^{4} - 10 {x}^{2} {y}^{2} + {x}^{3} y + {3x}^{4} + {2x}^{2} {y}^{2} - 9 {y}^{4}$

$(- 4 {y}^{4} - 9 {y}^{4} ) + ( - 10 {x}^{2} {y}^{2} + {2x}^{2} {y}^{2}) + 9 {xy}^{3}+ {x}^{3} y + {3x}^{4}$

$- 13 {y}^{4} - 8 {x}^{2} {y}^{2} + 9 {xy}^{3} + x {}^{3} y + 3x {}^{4}$

$- 13 {y}^{4} + {3x}^{4} - 8 {x}^{2} {y}^{2} + {x}^{3} y + {9xy}^{3}$
