Answer:
(a) check the first one, and the second one
(b) check the last one
Step-by-step explanation:
This is quite easy actually.
<h2>
(A)</h2>
3x+24 = 3 * x + 3 * 8
3(x+8) using distribute property.
3x + 24
You cannot simplify 3x+24 any further
And 3(8x+1) just doesn't work
since it's multiplying
The "*" is an X sign
<h2>
(B)</h2>
The first, second, and third are not correct
But the last one is.
External angle is equal to the sum of the other 2 internal angles
2x=x-5+63
minus x from both sides
x=-5+63
x=58
x=58°
How can I ask questions without answering questions it’s kind of annoying
Answer:
b < 5
Step-by-step explanation:
-2+b<3
Add 2 to each side
-2+2+b<3+2
b < 5
The appropriate choice is ...
(25−2x)(20−2x)x
_____
When x is cut from each side of the 25 dimension, the remaining dimension of the bottom of the box is 25-2x. Similarly, when x is cut from each side of the 20 dimension, the remaining dimension of the bottom of the box is 20-2x. The length of the side that is folded up is x, so that is how deep the box is.
The volume is the product of the dimensions of the bottom and the side:
(25−2x)(20−2x)x
