Answer:
1. 1,016 sq. m.
2. 119 sq. m.
Step-by-step explanation:
1.
14 x 18 = 252
18 x 8 = 144
14 x 8 = 112
2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )
504 + 288 + 224 = 1,016 sq m
2.
4 (7 x 5 divided by 2) + (7 x 7) =
7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.
I hope this helps
sorry if i'm wrong
Answer:
x=3. y=6
Step-by-step explanation:
So, to solve x and y, we need to take the equivelent sides of the two triangles, take their equations, and solve them.
So to find what x equals, we can take the 13, and make it equal to the 4x+1:
13=4x+1
Subtract the one from both sides:
12=4x
Divide both sides by 4:
3=x
Or
<u>x=3</u>
So we know the x value is 3.
Now lets solve for y using the bottom equations:
2x+y=8x-2y
Subtract 1y from both sides:
2x=8x-3y
Subtract 8x from both sides:
-6x=-3y
Divide both sides by -6:
x=1/2y
So we already know that x=3, lets plug that in for x, and solve for y:
3=1/2y
Or
1/2y=3
Multiply both sides by 2 to get 1y:
<u>y=6</u>
So we know that y is equal to 6.
Hope this helps!
