I added a screenshot with the complete question.

Answer:
area of larger triangle = 560 in²

Explanation:
We are given that the ratio between the side length of the larger triangle to the smaller one is 4:3
We can use this information to get the ratio between their areas.
To get the ratio between the areas, we will simply square the ratio between the side lengths as follows:
                    area of large triangle : area of small triangle
                                 (4)²                :            (3)²
                                 16                  :             9

We are given that the area of the small triangle is 315 in², therefore, we can use cross multiplication to get the area of the large triangle as follows:
                   area of large triangle : area of small triangle
                                 16                :            9
                                  ??               :            315
area of large triangle = (315*16) / 9
area of large triangle = 560 in²

Hope this helps :)

Determine whether the parabola y = −x2 + 15x + 8 opens up, down, left, or right.

Dy/dx=-2x+15

d2y/dx2=-2

Since the acceleration is a constant negative it has an absolute maximum value for y(x), thus it opens downward, as x decreases without bound as x approaches ±∞

Write an expression to represent the perimeter of the figure below. rectangle with 2x-3 and x+2
In-s [12.5K]
Hi there! 

The perimeter is when you add all the sides of a shape. In a rectangle, two sides are the same, and so are the other two. So, if the two sides are 2x-3 and x+2 the expression will be: 

2(2x-3) + 2(x+2) 

If we were to simplify this, it would be 

4x-6+2x+4 
6x-2

Hope this helps!
