For this case we have the following expression:

Rewriting the expression we have:

Where,
x: exponent to which we must raise the expression to obtain 7 as a result.
We have then:

The exponent must be equal to 1:

Clearing x we have:

Substituting valres:
Answer:
you must raise the expression to 2
C 15 x 12 =$180 plus $8 shipping is $188.00
Answer:
<h2>1. x = 4</h2><h2>2. x = 20</h2>
Step-by-step explanation:
1.
ΔABC and ΔAJK are similar (AA). Therefore the sides are in proportion:

We have:
AC = 1 + 4 = 5
AJ = 1
AB = 1 + x
AK = 1
Substitute:

<em>subtract 1 from both sides</em>

2.
ΔVUT and ΔVMN are similar (AA). Therefore the sides are in proportion:

We hve:
VU = x + 8
VM = x
VT = 49
VN = 49 - 14 = 35
Substitute:
<em>cross multiply</em>
<em>use the distributive property a(c + b) = ab + ac</em>
<em>subtract 35x from both sides</em>
<em>divide both sides by 14</em>

That would be a 45 degree angle
