The temperature changes can be represented by the expression -0.5( 1 -2h).Chase says that the temperature change can also be rep
resented by 4(2h+2)-7h-8.5 is chase correct? Are both expressions equivalent
1 answer:
Answer:
The expression are equivalent
Step-by-step explanation:
The question requests that we show whether the equation -0.5( 1 -2h) is equivalent to 4(2h + 2) - 7h - 8.5 or not :
Simplifying 4(2h + 2) - 7h - 8.5 ; we have ;
4(2h + 2) - 7h - 8.5
8h + 8 - 7h - 8.5
8h - 7h + 8 - 8.5
h - 0.5
-0.5(1 - 2h)
-0.5 + h
= h - 0.5
Hence, both expressions are the same

ax^2 + bx + c
x^2 + 12x + 3 = 7
x^2 + 12x = 4
Take b, half it, then square it--
x^2 + 12x + 36 = 40
That equation becomes
(x+6)^2 = 40
+ 6 = ± (square root of 40)
= 0.324555
= −12.3246
