The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.

A=1/2(9)(4)

Multiply to get 18 square cm, which is choice D.

Easiest question I have ever seen! :)
We know the formula of the area of a triangle
= $\frac{1}{2}$ ×base×height
The height given is 4 cm (we should take the perpendicular height)
And the base length is 8 cm
Simply, we just substitute the given numbers
= $\frac{1}{2}$ ×8×4
=18 cm²
The answer is D: 18 square m

Do you think there are any ordered pairs that are solutions to BOTH y = x + 5 and y = –2x – 1? Explain.

zloy xaker [14]

Answer:

The ordered pair is $(-2,3)$

Step-by-step explanation:

$y=x+5\\y=-2x-1\\\implies x+5=-2x-1\\\implies 3x=-6\\\boxed{x=-2}\\\implies y=-2+5=\boxed {3}\\$

Answer:

The length between the two points is RT = 1.3 units

Step-by-step explanation:

The coordinates of the point R and T are R(2,1.2) and T(2,2.5).

Now, by DISTANCE FORMULA:

The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:

$PQ = \sqrt{(a-c)^2 + (b-d)^2}$

So, here the distance RT = $\sqrt{(2-2)^2 + (2.5 - 1.2)^2} = \sqrt{0^2 + (1.3)^2} = 1.3$

or, RT = 1.3 units

Hence, the length between the two points is RT = 1.3 units
