ANSWER
80 units²
EXPLANATION
One way to solve this is to find the area of the blue square and the subtract the areas of the red triangles:
The blue square is 12 units long by 12 units wide. Its area is:
Then, the area of the big triangle, which has a base 12 units long and a height of 10 units, is:
The smaller triangle has a base of 4 units and a heigth of 2 units. Its area is:
So the total area of the figure is:
Answer:
c) 15m + 2n
Step-by-step explanation:
8m+4n+7m−2n
Combine like terms
8m+7m +4n−2n
15m +2n
1.63636363

(-7x)(9-2x)
-63x+14x
-49x is the answer
Answer:
x = 2
Step-by-step explanation:
I used the process of substitution to do this.
<em>1. put </em><em>both</em><em> equations into </em><em>slope-intercept form:</em>
y = 3x - 5
y = -2x + 5
<em>2. since they </em><em>both equal y</em><em>, they must </em><em>equal each other:</em>
3x - 5 = -2x + 5
<em>3. </em><em>simplify:</em>
2 = x
