Answer:(2x+5)(x+5)=0
Step-by-step explanation:
2x^2+15x+25=0
Factorise we have
2x^2+10x+5x+25
(2x^2+10x)+(5x+25)=0
2x(x+5)+5(x+5)=0
(2x+5)(x+5)=0
Answer:
x = 25 , y = 19
Step-by-step explanation:
Since the triangle has 3 congruent sides then it is equilateral
The 3 angles are also congruent, with each angle = 60° , then
2x + 10 = 60 ( subtract 10 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
and
3y + 3 = 60 ( subtract 3 from both sides )
3y = 57 ( divide both sides by 3 )
y = 19
4/7 of his money = $48
1/7 of his money = $48 ÷ 4 = $12
7/7 of his money = $12 x 7 = $84
Answer: $84
Answer: -1
Step-by-step explanation: f(x) is another way of saying y. So when y is 3, according to the table, x is -1
