Answer:
Step-by-step explanation:
A) 3x²c² + 5xc² - 2c²
Factor c² from all terms in the expression.
c²(3x² + 5x - 2)
Factor 3x² + 5x - 2
c²(3x-1)(x+2)
B) x² + 6x + 9
x² + 3x + 3x + 9
Factor common terms.
x(x+3)+3(x+3)
Take x+3 common.
(x+3)(x+3)
C) x² - 9
x² -3²
Apply formula : a² - b² = (a+b)(a-b)
(x+3)(x-3)
If the figure is drawn in a 2/5 scale, this means that all the length will be multiplied by 2/5. The area is a two-dimensional thing, so it would be multiplied by that factor twice, or 4/25. You can try checking all the lengths. The correct one should match all of the things I said above.
The answer is the top left one.
Answer:
b= -3
x= -2
x= -7
n = -6
Step-by-step explanation:
3b+7-1=-3
3b = -3 -7 +1
3b = -10+1
3b= -9
b = -9/3
b= -3
3x+1-6x=7
-3x = 7-1
-3x= 6
x= -6/3
x= -2
312=-6(7x-3)
312 = -6*7x +6*3
312= -42x +18
312-18= -42x
294 = -42x
x= -294/42
x= -7
-4(4n-8)=128
-4*4n +4*8 =128
-16n +32 = 128
-16n= 128-32
-16n = 96
n=-96/16
n = -6

Step-by-step explanation:
<u>Step 1: Define</u>
-3(3p - 1) < 7p + 51
<u>Step 2: Solve for </u><em><u>p</u></em>
- Distribute -3: -9p + 3 < 7p + 51
- Add 9p to both sides: 3 < 16p + 51
- Subtract 51 on both sides: -48 < 16p
- Divide 16 on both sides: -3 < p
- Rewrite: p > -3
Here we see that any value <em>p</em> greater than -3 would work as a solution to the inequality.
