Answer:
x=8
Step-by-step explanation:
2x+7 = 23
2x=16
x=8
An artist wants to frame a square painting with an area of 400 square inches.
(a) x is the length of one side of the painting
Area of the square formula is
side is x. so area becomes
We know Area is 400. so the equation becomes
(b) Solve the equation for x
(take square root on both sides)
When we take square root we put +-
+-20 = x
x = +20 in and x=-20in
So there are two solutions for the above equation.
(c)No. we know x is length of the side. the length cannot be negative .
So x=-20 inch is not valid
x=20 inches is our only solution.
(d)To find the length of the wood trim needed to go around the painting, we find the perimeter of the square
Perimeter = 4* side
= 4* x = 4* 20 = 80 inches

A locus is a set of a given <u>point</u> that <u>satisfies</u> <em>certain/ stated</em> <em>conditions</em>. This could be in the form of a <u>curve</u>, <u>circle</u>, or <u>line</u>. The required <u>construction</u> is wherewith attached to this answer.
<em>Construction</em> is a topic that requires following some <u>steps</u> to complete or solve a given question. This majorly requires the use of <em>materials</em> and <em>instruments</em> for <u>drawing</u> the expected figure.
A locus is a set of a given <u>point</u> that <em>satisfie</em>s some given <u>conditions</u>. This could be in the form of a <u>curve</u>, <u>circle</u>, or <u>line</u> satisfying the required <em>condition(s)</em>.
An <em>equidistant locus</em> is one that is at the same distance to a reference <u>point</u> or a <u>line</u>.
In question 14, the required locus should be at the same <u>distance</u> to <u>points</u> A, B, C, and D.
In question 15, the required locus should be at the same <u>distance</u> to <u>sides</u> KJ and KL. This should <u>pass</u> through point C.
The required <em>construction</em> is herewith attached to this answer.
