Answer:
Step-by-step explanation:
As the triangles are similar :
45/55 = (12x - 3)/143
9/11 = (12x - 3)/143
9 x 13 = 12x - 3
12x = 117 + 3
12x = 120
x = 10
Answer:
-3/2+√29/2 or -3/2-√29/2
Step-by-step explanation:
When the graph intercepts with x-axis, the value of y is zero.
So substitute y with zero.
The answer is the second choice, or B; 240 ft^2.
You have to find the area of all four triangles and just add those all together.
Two of the triangles have an area of
5*16=80
Multiply that by two
80*2=160
The other two smaller triangles have an area of
8*5=40
Multiply that by 2 also
40*2=80
Add 160+80 and the answer is 240.
No she did the Division wrong because she got 5 1/2 for her multiplication it so she should recheck and try the multiplication over to get the answer right
