Answer:
To simplify:
(3x+4y) - (x-y) = 2x + 5y
To factorize:
(5p + 6)(5p -6)
Step-by-step explanation:
Answer:
Given a is 5
Step-by-step explanation:
I. Given a is 5
= a + 1
= 5 + 1
= 6
6 is divisible by 3 => true
II. Find 4 + 7a value
= 4 + 7(5)
= 4 + 35
= 39
39 is divisible by 3 => true
III. Prove by
6 ÷ 3 = 3
39 ÷ 3 = 13
Hope that help :)
Answer:
y=5x+4
Step-by-step explanation:
With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256
Answer = 1256
Answer:
x = -6, 6
Step-by-step explanation:
Isolate the variable, x. Find factors of all terms on the left:
x² + 36 = 0
x 6
x 6
(x + 6)(x + 6) = 0
Solve for x:
(x + 6) = 0
x + 6 = 0
x + 6 (-6) = 0 (-6)
x = -6
x² + 36 = 0
x -6
x -6
(x - 6)(x - 6) = 0
Solve for x:
x - 6 = 0
x - 6 (+6) = 0 (+6)
x = 6
x = -6 , 6.
