Answer:
-4
Step-by-step explanation:
(2^2)3 - (10 - 6) ^2 x 4 - 5 =
(4)3 - (4)^2 x 1 =
12 - 16 x 1 =
- 4 x 1 = -4
Answer:
Step-by-step explanation:
Given the equations
solving the system of the equation by elimination method
solve 45y=5 for y:
solve 
for x:
Add 36 to both sides
Answer:
18/3
Step-by-step explanation:
6x3=18
Answer:
B) Only (-3, 5)
Step-by-step explanation:
Slot in the options into the equation
(-2, 4),
Compare with (x, y)
x = -2, y =4
y =-3x - 4
4 =( -3 * -2 ) - 4
4 = 6 - 4
This is not true hence, option A is wrong
Using (-3, 5)
x = -3, y= 5
5 = (-3*-3) - 4
5 = 9 - 4
This is correct hence, option B is correct
Option c is wrong because (-2,4) is not a solution to the equation
Option D is wrong because option B is correct
P=2*(L+l)=46
L+l=46:2
L+l=23
(L+l)^2=529
(L^2+l^2)+2l*L=529
D= V L^2+l^2= 17
L^2+l^2=289
so 289+2l*L=529
2l*L=529-289=240
l*L=240:2
A=120
