Answer:
The lengths of all sides of the triangle will be 21 cm, 21 cm, and 21 cm
Step-by-step explanation:
Given that the perimeter of the triangle = 63 cm
And the length of one side = 21 cm
and one of the medians is perpendicular to one of its angle bisectors
Since triangle has 3 sides,
Median = 63 ÷ 3 = 21
Therefore each side length = 21 cm
Answer:
1020 students
Step-by-step explanation:
Given the trend line equation :
y = 0.1x + 18,
where y is the total number of staff members and x is the total number of students.
Using the equation, the predicted number of students in a school with 120 staffs ;
y = 120
y = 0.1x + 18
120 = 0.1x + 18
120 - 18 = 0.1x
102 = 0.1x
x = 102 / 0.1
= 1020 students

Hello,
Answer B
x^4-52x²+576=0
==>x^4-16x²-36x²+576=0
==>x²(x²-16)-36(x²-16)=0
==>(x²-16)(x²-36)=0
==>(x+4)(x-4)(x+6)(x-6)=0
It’s a process of bringing one variable to the side with different forms of mathematical properties. First, subtract 2 from the left side and add it to the right side. Then divide 1/4x by 1/4 to get x alone, and divide the right side (-2) by 1/4, which will give you the answer to x. Let me know if you need help with anything else!
