Answer:
Area of rectangle: 256
Area of triangle 1: 24
Area of triangle 2: 16
Area of triangle 3: 96
Area of trapezoid: 120
Step-by-step explanation:
I just did the question on the thing so Ik I'm right.
-The graph measures by twos. To get the area of the rectangle get the base times height of it. That would be 16x16=256.
-Get base (8) times height (6) of triangle 1 then divide by 2, remember to count the squares by 2 for finding all areas. The formula would be 1/2(b)(h) because dividing by 2 is the same as multiplying times 1/2. Plug it in and (8)(6)=48 then divide by 2 which equals 24.
-Same formula for triangle 2. Plug it in and (8)(4)=32 and divide by 2 and it equals 16.
-Same formula for triangle 3. Plugged in is (12)(16)=192 divide by 2 and it equals 96.
-To find the area of the trapezoid get your rectangle area (256) and subtract all the triangle areas. So 256 - 6 - 16 - 96 = 120.
Answer: 2b+3
Combine like terms which are 5 and -2
Answer:
x=112
Step-by-step explanation:
First, let's get all of the fractions to a common denominator.
Based on the numbers given (8,56, and 7), let's make all of the denominators be 56
for 
, multiply the numerator and denominator by 7.
×
= 
we can leave 
as it is
and for 
, we cam multiply the numerator and denominator by 8
×
=
Here's the equation now:
-
+=-92
now simlify the fractions
numerators:
-49x-5x+8x=-46x
here's the fraction now:
=-92
We can simplify the fraction by 2 so it's 
=-92
now multiply both sides by 
, which is the reciprocal of 
(to isolate the variable)
×=-92×
x=112
Hope this helps!
