12/15 = 8/x
Cross multiply:
12*x = 8*15
⇒ 12*x= 120
⇒ (12/12)*x = 120/12
⇒ x= 10.
Final answer: x=10.
Hope this helps~
Answer:
Step-by-step explanation:
√(4t+5) = 3
4t + 5 = 9
4t = 4
t = 1
A) Net A would be the correct net for the prism.
B) AB = 3in
BC = 5in
CD = 8.6in
C) area of one triangle : 4*3/2 = 6
But there's 2 triangles so 6*2 = 12cm2
Area of the middle square : 8.6*4 = 34.4cm2
Area of bottom square : 8.6*5 = 43cm2
Area of top rectangle : 8.6*3 = 25.8cm2
Finally add all of these areas together and you will get the surface area : 115.2cm
Answer:
The system consists of parallel lines, and the both lines have the same slope.
Step-by-step explanation:
The slope is the coefficient of x. (The coefficient of y should be 1)
When the slopes are equal, it means they are parallel.
