-30 is the answer for your question
Volume of the bottom rectangle:
12 x 4.5 x 5.5 = 297 cubic cm
Volume of triangle:
1/2 x 12 x 5 = 30 x 4.5 = 135 cubic cm
Total volume = 297 + 135 = 432 cubic cm
Yes it does, to find this insert the values of x and y into the equation.
14>-11
We can easily silve it by splitting the middle term or by using the discriminate method *
<h3>* <u>splitting</u></h3>
x 2 +3x -70
x2 + 10x - 7x -70
x(x + 10) -7(x +10)
(x / 7) ( x + 10)
x = 7 or -10
Answer:
(4,1)
Step-by-step explanation:
2x+4y=12
y=x-3
2x+4*(x-3)=12
2x+4x-12=12
6x=24
x=4
y=4-3=1
