I think 2,3,4 or B,C,D would be correct.

The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h

1) 8(6) = 48/2 =24

2) 9(10 2/3) = 96/2 =48

3) 19.2(2.5) = 48

4) 16(3) = 48

Hope this is right and hope it helps. Have a good day

The figure shows △XYZ. XW⎯⎯⎯⎯⎯⎯ is the angle bisector of ∠YXZ .<br><br> What is WZ ?
Mnenie [13.5K]
Use the law of cosines to find the measure of angle YXZ.

8^2=6.5^2+6^2-2(6.5)(6)\cos(\angle YXZ)
\cos(\angle YXZ)\approx0.1827
\angle YXZ\approx 1.3871\text{ rad}\approx79.4734^\circ

This means angles YXW and WXZ share the same measure of about 39.7367^\circ.

Use the law of cosines again to find the measure of angle XZW.

6.5^2=8^2+6^2-2(8)(6)\cos(\angle XZW)
\cos(\angle XZW)\approx0.6016
\angle XZW\approx0.9253\text{ rad}\approx53.0181^\circ

This means the measure of angle XWZ is

180^\circ=\angle WXZ+\angle XWZ+\angle XZW\implies \angle XWZ\approx87.25^\circ

Now using the law of sines, you have

\dfrac{\sin(\angle WXZ)}{WZ}=\dfrac{\sin(\angle XWZ)}6\implies WZ\approx3.84

(3x2 + 10x + 3) by (x + 3)​
Nata [24]
Explanation: 3 x 2 + 10 x + 3 We can Split the Middle Term of this expression to factorise it. In this technique, if we have to factorise an expression like a x 2 + b x + c , we need to think of 2 numbers such that: N 1 ⋅ N 2 = a ⋅ c = 3 ⋅ 3 = 9 and, N 1 + N 2 = b = 10 After trying out a few numbers we get: N 1 = 9 and N 2 = 1 9 ⋅ 1 = 9 , and 9 + ( 1 ) = 10 3 x 2 + 10 x + 3 = 3 x 2 + 9 x + 1 x + 3 = 3 x ( x + 3 ) + 1 ( x + 3 ) ( 3 x + 1 ) ( x + 3 ) is the factorised form for the expression.

c
, we need to think of 2 numbers such that:
N

and,

After trying out a few numbers we get:
N

and

is the factorised form for the expression.
