Answer:
255
Step-by-step explanation:
12x^(2) + 39x + 30
x = 3
Substitute in"3" for "x" and solve;
12(3)^(2) + 39(3) + 30
= 12 * 9 + 117 + 30
= 108 + 117 + 30
= 255
Answer:
Step 2
Step-by-step explanation:
Step 2 is not correct. It should be abs(25 - - 26) = abs(25 + 26) = 51
Given that Step 2 is accepted (as - 1) then three is OK and and so is 4. But technically they are incorrect as well. I think you are likely to say that step 2 is the problem.
8x4x11 - (4x1x3)
352 - 12
= 340
The answer is 340yd^3
Answer:
(4, 5)
Step-by-step explanation:
5x + y = 25
-3x + 2y = -2
5x + y = 25
y = 25 - 5x
-3x + 2 * (25 - 5x) = -2
-3x + 50 - 10x = -2
-13x = -52
x = 4
5 * 4 + y = 25
20 + y = 25
y = 5
Solution: (4, 5)
