Answer: C) Cannot be done

Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.

F(x) = 2x – 1 g(x) = 7x – 12 What is h(x) = f(x) + g(x)?

WINSTONCH [101]

Answer:

Solution,

 $h(x) = f(x) + g(x) \\ \: \: \: \: \: \: \: = 2x - 1 + 7x - 12 \\ \: \: \: \: \: \: = 2x + 7x - 1 - 12 \\ \: \: \: \: \: \: = 9x - 13$ 

hope this helps...

Good luck on your assignment..

Iteru [2.4K]

Answer:

x=52

Step-by-step explanation:

90+34

124

180 (sum of all interior angles) - 124

x+72+56=180 (straight line)

x+128=180

-128 -128

x=52

*replace to verify*

52+72= 124

124+56= 180 (straight line)

Will someone please help me!!! I don’t know the answer to these! I don’t even know if I did them right!

Answer:

$BD = 12$ units

$AB = 16$ units

$FG=\sqrt{105}$

$EC=4\sqrt{10}$ units

$AC=8\sqrt{10}$ units

Step-by-step explanation:

A circumcenter is the point where the perpendicular bisectors of a triangle intersect.

This means

BD = DC;
BF = FA;
AE = EC.

Since BC = 24 units, then BD = 12 units (half of BC).

Since FA = 8 units, AB = 16 units (twice FA).

Consider right triangle BGF. In this triangle, BF = 8 units (congruent to FA), BG = 13 units. By the Pythagorean theorem,

$FG^2=BG^2-BF^2\\ \\FG^2=13^2-8^2\\ \\FG^2=169-64=105\\ \\FG=\sqrt{105}\ units$

Triangles BFG and AFG are congruent right triangles, then BG = AG. In right triangle AGE, $GE=3$ units, $AG=13$ units. By the Pythagorean theorem,

$AE^2=AG^2-GE^2\\ \\AE^2=13^2-3^2=169-9=160\\ \\AE=\sqrt{160}=4\sqrt{10}\ units$

$AE = EC=4\sqrt{10}\ units$

$AC = 2AE=2\cdot 4\sqrt{10}=8\sqrt{10}\ units$
