4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==> 6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9 because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.
Answer:
60% i got it
Step-by-step explanation:
6000/500= 12
12/20*100= 60%
Answer:
12
Step-by-step explanation:
Step-by-step explanation:
Let the painting's width be w inches and length be l inches.
w + 6 = 2l
w = 2l - 6 --(1)
2w + 2l = 84 --(2)
sub (1) into (2):
2(2l - 6) + 2l = 84
2l - 6 + l = 42
3l = 48
l = 16
when l = 16, w = 2(16) - 6 = 26
area of painting = lw = 16 x 26 = 416square inches
Therefore, only statements 1, 3 and 5 are true

Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
