Answer:63
Step-by-step explanation: H:0=18:12=1.5:1
1.5:1=63:42
Step-by-step explanation:
if n=5
5-10+9(5)-3
-5+45-3
45-8=37
if n=-9
-9-10+9( -9)-3
-19-81-3=-103
Answer:
-24
Given expression:
3z (2y - 4)²
z = -2 and y = 3
To solve this problem, simply substitute:
3z (2y - 4)² = 3(-2){2(3) - 4}²
= -6(6-4)²
= -6 (2)²
= -6 x 4
= -24
step by step
A=1/2h(B+b)
15=1/2h(4+1)
15/(4+1)=1/2h
15/5=1/2h
3=1/2h
h=2*3
h=6
20.4
