Answer:
150
Step-by-step explanation:
The are is the sum of are of square and area of triangle.
A=A1+A2
A1=a*a=10*10=100
A2=a*h/2=10*10/2=50
A=100+50=150
Answer:
12+34=46
A=38
B=58
C=46
the answer is student c writes
Find a common denominator, then add and simplify
Steps to solve:
3^2 • 3^-8 • 3^0
~Apple exponent rule [ a^b * a^c = a^b+c ]
3^2-8+0
~Simplify
3^-6
~Use exponent rule [ a^-b = 1/a^b ]
1/3^6
~Simplify
1/729
Best of Luck!
Answer:
89 meters
Step-by-step explanation:
We know it's 9 + "the height of the triangle".
Fortunately, the height of the triangle (let's call it y) can be computed from:
y^2 + 18^2 = 82^2 (Pythagoras theorem).
y^2 = 82^2 - 18^2 = 6724 - 324 = 6400
y = 80 (or y = -80 but it doesn't make sense in geometry).
so x = y + 9 = 89;
