Answer:
c) x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)?
=15x-10=10+6+2x
=15x-2x=10+6+10
=13x=26
=13x/13=26/13
=therefore X=2
Answer:
B.-38
Step-by-step explanation:
2x - 18 = y ...(1)
x = -10 (Given)
Now,
Put the value of x in equation (1) we get,
2(-10) - 18 = y
-20 - 18 = y
-38 = y
<em><u>y = -38</u></em>
Thus, the value of y is -38
Answer:
2(x + 1)(x - 5)
Step-by-step explanation:
First you need to find the GCF (greatest common factor). Each term has 2 in common. Factor the 2 out of each term. 2(x²- 6x + 5)
Next you need to solve inside the parenthesis with an x-puzzle. 2(x+1)(x-5)
Check your answer by multiplying. You should get the expression you began with. 2x² - 12 + 10
