Answer:
158cm
Step-by-step explanation:
Martine had the height of 50cm when born.
Every year she grows at an average rate of 6cm
So the the first 18 years will be 6cm × 18 = 108cm
She will be 108cm + 50cm = 158cm tall by the time she turns 18 years
50cm + (6 × 18)cm
50cm + (6 × 18)cm50cm + 108cm
50cm + (6 × 18)cm50cm + 108cm158cm

Step-by-step explanation:
Answer:
x = 8
measure of each side = 27 units
Step-by-step explanation:
Properties of an <u>equilateral triangle</u>:
- Regular polygon with 3 sides
- All 3 sides are <u>equal in length</u>
- All 3 interior angles are congruent
If ΔGHJ is an equilateral triangle, the side measures are equal.
To solve for x, choose 2 side lengths, equate them, and solve for x:
To find the measure of each side, substitute the found value of x into one of the side expressions:
Therefore, x = 8 and the measure of each side is 27 units.
C, i think you forgot an x
(x+11)+(x-7)
x+11+x-7
x+x+4
2x+4
