Step-by-step explanation:
area of a rectangle=l*w which is 40*14=560
area of a square=30^2=900
900+560=1460
6.
the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).
[just put a dot on the number four that's right under the letter y]
the slope of the line is positive, so it goes up from left to right.
Start at the y-intercept. Move up 2 and then move right 1.
You are now at the point (1,6).
[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]
7. y= -1/2-3
8. y=3x+4
Explanation:
We will use the Pythagorean Theorem to determine if these lengths for a right triangle.
This theorem states, for a right triangle:
<span><span>a2</span>+<span>b2</span>=<span>c2</span></span>
Where a and b are the base and height and c is the hypotenuse which is also the longest length.
Substitute the values into this equation and see if both sides of the equation are equal. If they are the lengths form a right triangle. If they are not equal then they would not form a right triangle.
<span><span>362</span>+<span>772</span>=<span>852</span></span>
<span>1296+5929=7225</span>
<span>7225=7225</span>
Because both sides of the equation are equal these lengths do form a right triangle.
