Answer:(4,-2)
Step-by-step explanation: elimination method
3(3x+5y)=2×3
9x+11y=14
9x+15y=6
-
9x+11y=14
4y=-8
y=-2
To get x replace y with -2
3x+(5×-2)=2
3×=12
X=4
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
Step-by-step explanation:
Answer:
the amount of soil needed is
Step-by-step explanation:
N/B: the width is 8 in
this problem bothers on the mensuration of solid shapes, rectangular prism
Given data
length l= 15 in
width w= 8 in
height h= 3/4 in
The amount of soil need in the flower box is equivalent to the volume of the box for the given data.

The square root of 25/64=5/8
