2(20+60+48)=2(128)= 256 square inches
Hope it helps
Answer:
10 units
Step-by-step explanation:
Area of a triangle is
= Area
where h is the height, and b is the base
We can substitute these values into the area equation and get:

Multiply both sides by 2:
x * 10 = 100
Divide both sides by 10:
x = 10
The missing side is 10 units long
Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
volume of A = 1728
volume of B = 729
<span> (1728 / 729) = (a / b)^3 (a = width of A, b = width of B)
a / b = cube root (1728 / 729) = 4/3 </span><span> b = 10 (given)
a / 10 = 4/3 </span><span>
a = 40/3 = 13.33333</span>
so width of A is 13.33m
Answer:
It is 5,-5
Step-by-step explanation:
when you have two numbers that are the same, but one is a negative, the sum will be zero. In this case you can read it as 5-5=0
