7^6 = 117649
7^5 = 16807
so now you multiply
Answer:
14981yd^2
Step by step:
1) surface area formula: SA=2bs+b^2
s=height
b=square of base
so
SA=2*71*70+71^2
SA=2*71*70+5041
SA=9940+5041
SA=14981
Answer:
18+18 as point XYZ is in centroid of Q
Step-by-step explanation:
so it's equal.
36.which is option A.

Answer: x = 5</h3>
============================================================
Explanation:
The square marker indicates a 90 degree, or right angle.
The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.
Add up the smaller angles, set the sum equal to 90, and solve for x.
3x+75 = 90
3x+75-75 = 90-75 ....... subtracting 75 from both sides
3x = 15
3x/3 = 15/3 ..... divide both sides by 3
x = 5
---------------
If x = 5, then 3x = 3*5 = 15
Then we can see that 15+75 = 90 to help check our answer.
It is three fourths less than one half of a number,
