You would use pythagoras theorem which would be

Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Answer:
20%
Step-by-step explanation:
First, I added them up. From the things we know, blue, red, green, yellow combined equals 16 marbles. 20-16 equals 4. So there are 4 white marbles. 4/20 times 5 equals 20/100. So the percent of the marbles that are white is 20%.
Answer:
Q. 2)Perimeter =2(l+b)
So,
2(8x-8 +8x)=80cm(Given in Question)
= 2*16x-8=80cm
16x- 8= 80 divided by 2,
16x=40+8=48
x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)
2(2x+8 +4x)=76cm(Given in Question)
2* 6x +8=76
6x+8= 76 divided by 2, 38
6x= 38-8, 30
x= 30 divided by 6 = 5
X=5
THANK ME LATER
We need to subtract 23 by 12
23-12=11
That means there are 11 girls
Your answer is 11:23
Hope this helped
