Surface area = base area + side area
= pi * 7^2 + pi * 7 * 27 = 238pi = 747.7 cm^2
Answer:
18j + 63 + 45j and 9(2j + 7) + 9(5j)
Step-by-step explanation:
distributive property
9(2j + 7 + 5j)
9× 2j + 9×7 + 9 × 5j
18j + 63 + 45j
associative property
9(2j + 7 + 5j)
9(2j + 7) + 9(5j)
(f+g)(x) = 4x^2+1+x^2-5 = 5x^2-4 l, so D.
Answer:
x=9
Step-by-step explanation:
2x+10=28
Subtract 10 from both sides
2x=18
Divide by 2 on both sides
x=9
Answer:
Dilate, Reflect
Not congruent, dilations are used
Step-by-step explanation:
Dilate the figure by a scale factor of 1/3
Reflecting the resulting shape will map the figure
Step 1: Dilate by 1/3
Step 2: Reflect over the y-axis
Since dilations are used, the figures are not the same, as it changes area and side lengths.
