Answer: -9

Step-by-step explanation:

"3 times -3" indicates a multiplication. Then, rewriting it, this is:

(3)(-3)

Now, in order to solve the given multiplication, the first thing you need to remember is multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(+)(-)=-

Notice that one factor is positive and the other one is negative. Then, the product will be negative.

Therefore, the product is:

 (3)(-3)=-9

I need help with this question ASAP!!!!!!!!!!!!!
Mazyrski [523]

The height of the flag pole is 51 ft.

Solution:

Paul creates the smaller triangle and flag pole creates the larger triangle.

Base of smaller triangle = 10 ft

Height of smaller triangle = 6 ft

Base of the larger triangle = 85 ft

Let the height of the flagpole be h.

$\Rightarrow \frac{6}{10} =\frac{h}{85}

Multiply by 85 on both sides.

$\Rightarrow 85 \times \frac{6}{10} =\frac{h}{85}  \times85

$\Rightarrow \frac{510}{10} =h

⇒ 51 = h

The height of the flag pole is 51 ft.
