Answer:
x=5
Step-by-step explanation:
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
x=5
Answer:
-15 < x < -5
Step-by-step explanation:
-3 < x/5 < -1
Multiply all sides by 5
-3*5 < x/5 *5 < -1*5
-15 < x < -5
Figure 1 has 8 tiles
figure 2 has 14 tiles
figure 3 has 22 tiles
I'm guessing the 2 on the side hints for us to do something+2
the inside parts are
figure 1: 6
figure 2: 12
figure 3: 20
hmm, the width is 1+number figure
height is 2+figure number
so therefor, figure x is (1+x)(2+x)+2
so the rule is figure x has (x+1)(x+2)+2 or

tiles
a. the rule is figure x has (x+1)(x+2)+2 or

tiles
b. it is quadratic because it has

in it
Just make the equation look like this y = mx + b
So 3x + y =10 would equal y = -3x + 10
