Answer:
7, 23
Step-by-step explanation:
R could lie either to the left of S or to the right of S on the number line
Therefore possible values for R are 15-8 = 7
and 15 + 8 = 23
We are told that f(x) = x + 2. We want to find .
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
Answer:
w= p-2l divided by 2 or w= p/2 -l. This is the letter l, not 1.
Step-by-step explanation:
Subtract both sides by 2l to isolate for 2w. Then, you have 2w= p-2l. You have to make w to the lowest terms or make it a coefficient of one. To do that, you have to divide everything by 2. 2w divided 2 is w, p/2 is p/2, and length is -2l divided by 2 which is -l. You could also just leave it as 2l-p that whole expression gets divided by 2. Hope this helps!
Answer:
i) let x be the amount of money worth of drinks that Kevin sold.
ii) Kevin sells at most $60 worth of drinks.

Answer:
The two angles ADB and BDC are congruent since they are both right angles.
The segment AD and CD are congruent since D is the midpoint of AC.
Segment BD is in common for the two triangles.
The triangles ABD and BCD are congruent by SAS. In particular, Angle A is congruent to angle C (they are opposite to congruent sides), QED
