Answer:

(x−1)(x+2)

Step-by-step explanation:

The middle number is 1 (1x) and the last number is -2.

Factoring means we want something like

(x+_)(x+_)  

We need two numbers that...

Add together to get 1

Multiply together to get -2  

Try -1 and 2:

-1+2 = 1

-1*2 = -2

Fill in the blanks in

(x+_)(x+_)

with -1 and 2 to get...

(x-1)(x+2)

Hope this helps!

dolphi86 [110]

Answer:

1.If you are to check  the figure you will find that it is a rectangles. You should know the properties of a rectangle.

  • we are goin to use the property: Each vertex of a rectangle has angle equal to 90 degrees
  • meaning since m∠SUT and m∠ RUS form the vertex when added they give 90°

3x+6+(5x-4)=90°

3x+5x+6°-4°=90°

8x+2°=90°

8x=90°-2°

8x=8°

\frac{8x}{8} =\frac{88}{8} \\x=11

2.m ∠SUT is donated by 3x+6

and now we know the value of x=11°

m∠SUT=3(11°)+6

m∠SUT=33°+6°

m∠SUT=39°

VARVARA [1.3K]

Answer:

90 bags of sand

Step-by-step explanation:

9 feet × 1.5 = 13.5

12 feet × 1.5 = 18

Large pit area= 13.5 × 18 = 243ft squared

The small pit area=9 × 12 = 108ft squared

243 / 108 = 2.25 times larger

This means the large pit needs 2.25 times more sand.

40 × 2.25 = 90 bags of sand
