Answer:
answer is y^2-6y+9
Step-by-step explanation:
first take out the value of x from equation 1 which is x=(2-y)
then put the value of x in equation 2 u will get ur answer as y^2-6y+9
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°
Answer:
x=3
Step-by-step explanation:
cross multiply
12.5*2=30
10*x=10x
10x=30
/10
x=3
Answer:
A: vertical angles
B: corresponding angles theorem
C: transitive property
Step-by-step explanation:
Hello!
To find the volume of a rectangular prism you use the equation
V = lhw
v is volume
l is length
h is height
w is width
Put in the values you know
180 = 6 * 5 * w
Divide both sides by 6
30 = 5 * w
Divide both sides by 5
6 = w
Answer is 6cm
Hope this helps!
