Answer:
b = 5
Step-by-step explanation:
if parallelogram is a rectangle, then the two diagonals has the same length
10/12 x(24/5 x b - 36/5) = 2/3 x (3b + 6)
4b - 6 = 2b + 4
2b = 10
b = 5
Answer:
533.6cm²
Step-by-step explanation:
Hello!
I'm here to answer your question!
<u>Area of each triangular base:</u>

<u />
<u>Area of the rectangular faces:</u>



<u>Add to find the surface area:</u>

Thus, the surface area of the triangular prism is = 533.6 yd²
Hope this helps you!
Hugs from,
Josh
The answer is b
The perimeter of a rectangle is 2(l + w) so in this case, it is 2(15 + 9) and that is equal to 48. But so at c and d. So u need to multiply the width by 2 (9*2=18) and then you’ll see that 18-3=15. And therefore, the length is -5 and the width is 9
Answer:
3x - 4y = 0
Step-by-step explanation:
The triangle Δ ABC has vertices A(0,0), B(0,4) and C(3,0).
Therefore, the equation of the straight line BC in intercept form will be
⇒ 4x + 3y = 12
⇒
.......... (1)
This is a equation in slope-intercept form and the slope is
.
Now, the altitude AR is perpendicular to equation (1) and hence its slope will be
.
{Since, the product of slope of two mutually perpendicular straight line is always - 1}
Therefore, the equation of the altitude AR which passes through A(0,0) will be
⇒ 4y = 3x
⇒ 3x - 4y = 0 (Answer)
The solution is “no real solution”
Because the slope is the same, so they are parallel.
Hope that help!! :-)
