Just saying if your looking for an answer you don't have to show work for it.
Answer:
25
Step-by-step explanation:
Let's call the missing side (the hypotenuse) c.
c² = 7²+24² (according to the pythagorean theorem)
c=
c=25
The three angles of a triangle add up to 180.
Since you know that two angles add up to 80, you know that the third angle is 100.
Answer:
3x³ + 29x² + 10x - 50
Step-by-step explanation:
(3x + 5))(x² + 8x - 10)
each term in the second factor is multiplied by each term in the first factor , that is
3x(x² + 8x - 10) + 5(x² + 8x - 10) ← distribute parenthesis
= 3x³ + 24x² - 30x + 5x² + 40x - 50 ← collect like terms
= 3x³ + 29x² + 10x - 50
Let l = length
Let w = width
l = 4w (length is 4x width)
2l + 2w = 100 (perimeter is two lengths and two widths)
2(4w) + 2w = 100 (substitute)
8w + 2w = 100 (solve)
10w = 100
w = 10
l = 4(10) (plug in)
l = 40
The length of the rectangle is 40in and the width is 10in.
