3. 8(3+8)
Explanation : 8x3 = 24 + 8x8 =64 which is congruent to 24 +64
Step-by-step explanation:
x + y = 72
x - y = 40
x = y + 40
so, the first equation is then
y + 40 + y = 72
2y + 40 = 72
2y = 32
y = 16
x = y + 40 = 16 + 40 = 56
Answer:
Solution 1
(x,y) = (-1,3)
Solution 2
(x,y) = (1,5)
Step-by-step explanation:
To easily solve this question, we use a graphing tool, or a calculator to plot each graph.
The solution of the system of equations corresponds to the intersection between both graphs
f(x)=x^2 + 4/4x + 3
g(x)=|x+4|
Please see image below
Solution 1
(x,y) = (-1,3)
Solution 2
(x,y) = (1,5)
Answer:
D
Step-by-step explanation:
Before the increase, the length is 6 and the width is 5, so the area is 5×6 = 30.
After the increase, the length is x+6, the width is x+5, and the area is tripled: 30×3 = 90.
Therefore:
(x+6) (x+5) = 90
3.6 ounces --> 5.9 ounces
4.2 ounces --> 6.5 ounces
3.3 ounces --> 5.6 ounces
You just basically add 2.3 ounces to each of the kitten's original weight.
