Answer:
10
Step-by-step explanation:
divide each side by -4
5x-1=-49
5x=50
x=10
Answer:
if you round of. 20 the answer is 10
Answer:
5238 * 7 = 36666
Step-by-step explanation:
Area of rectangle is given by:
Area=length*width
let the length be l
the width width will be:
w=192/w
but Pythagorean theorem is given by:
c^2=a^2+b^2
thus plugging in the values we get:
20²=w²+(192/w)^2
400=w²+36864/w²
solving the above we get:
w=-16, w=-12, w=12, w=16
thus the dimensions are 12 inches by 16 inches
It will help to graph it, so that you can see the shape. However, you can also just solve it by looking at the vertices. If you graph it, you'll see that the shape is a trapezoid. The two bases are 4 and 6, while the height is 5 - 1 = 4. So, we solve by using the equation for the area of a trapezoid: (6 + 4) * 4 * .5 = 20 units squared.
