-7/16 - 1/4 - 5/16
1. -7/16 - 4x1/4x4 - 5/16
2. -(7/16 + 4/16 + 5/16)
3. -7 + 4 + 5/16
that will add up to be 16/16 then cancel them out and you get for your answer -1
Answer:
y = 4/7 - 4
Step-by-step explanation:
Slope = (-4-0) / (0 - 7) = -4/-7 = 4/7
y-intercept: -4 - (4/7)(0) = -4
Answer:
<h2>231cm²</h2>
Step-by-step explanation:
First, let's find the surface area of both the triangles
5x3=15
So, the surface area of the triangles is 15 sq.cm
Now, let's find the surface area of the base (large rectangle in the middle)
12x8=?
10x8=80
2x8=16
80+16=96
12x8=96
So, the surface area of the base, is 96sq.cm
Now, let's find the surface area of both of the side rectangles
12x5=60
60x2=120
So, the surface area of the two side rectangles is 120sq.cm
Now, let's find the total surface area by adding all of our answers.
120+96=216
216+15=231
<h2>
So hence, the surface area of this net is 231cm²</h2>
Answer:
To find the missing side we need to calculate the sum of the two given sides and then subtract that from the perimeter.
7a - 11b - (2a + b + a - 9b)
= 7a - 11b - (3a - 8b)
= 7a - 3a - 11b + 8b
= 4a - 3b
