Step-by-step explanation:
Hello
Which expression is equivalent to 1/3 (5x + 3y) + 2/5y + 7 ?
a. 5/3x + 2/5y + 7
b. 5/3x + 7/5y + 7
c. 15x + 9 2/5y + 7
d. 15x + 2/5y + 7
1/3 (5x + 3y) + 2/5y + 7
= 5/3 x + y + 2/5 y + 7
= 5/3 x + 5/5 y + 2/5 y + 7
= 5/3 x + 7/5 y + 7
Answer : b
Answer:
(a + b + c)(a + b - c)
Step-by-step explanation:
(a + b)² - c² ← is a difference of squares and factors in general as
x² - y² = (x + y)(x - y)
Here x = a + b and y = c , then
(a + b)² - c²
= (a + b + c)(a + b - c)
Answer:
answer is -9
Step-by-step explanation:
5(x+1)=4(x-1)x
5x+5=4x-4+x
5x+5=4x+x-4
5x+5=5x-4
5x-5x=-4-5
x=-9
