Y=15 if the sides are corresponding the scale factor would be 2.2 (22/10) meaning to find y do 33/2.2 i thiiiink
57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
We have that
surface area of the cylinder=2*[pi*r²]+[2*pi*r*h]
r=(4x+3)
h=3*r=3*(4x+3)
S=2*[pi*(4x+3)²]+[2*pi*(4x+3)*(3*(4x+3))]------> 2*[pi*(4x+3)²]+[6*pi*(4x+3)²]
S=8*pi*(4x+3)²----> 8*pi*[16x²+24x+9]-----> 402.12 x²+603.19x+226.19
the answer is S=402.12 x²+603.19x+226.19 (8pi[16x²+24x+9])
expanding the brackets makes this:
-63g – 36 + 14g² + 8g
simplifying it more makes this:
14g²–55g–36
hope that helped:)
The missing angle is ninety degrees (Brainliest please)
