Answer:
p=7/2=3.5
Step-by-step explanation:
(5p-8)/2=(7p+4)/6
cross product
2(7p+4)=6(5p-8)
14p+8=30p-48
8=30p-14p-48
8=16p-48
16p=8+48
16p=56
p=56/16
p=7/2=3.5
The top one. they can't be expressed in a fraction or decimal
Use the Pythagorean theorem:
70^2 = 42^2 + width^2
4900 = 1764 + width ^2
Subtract 1764 from both sides
3136 = width^2
Take the square root of both sides
Width = 56 inches
Area of triangle = 1/2 x base x height
so old triangle we have 1/2 x b x h = 48
new triangle has base 3 times as long and height is half as long
so we would get:
1/2 x (3B) x (1/2H) = area
rewrite as 1/2 x 3/2 x b x H = area
divide by original are os 1/2 x b x h and you end up with 3/2
so new area = 3/2 x old area
new area = 3/2 * 48 = 72 square inches
