Answer:
1064.8 in^2
Step-by-step explanation:
12.1 x 17. 6 / 2 to find one half of a triangle will equal 106.48
there are 10 triangle therefore 106.48 x 10 = 1064.8
A-$70 is the correct answer, even though im not sure.
Answer is 125.
Because it's cube root is an integer:)
Answer:
length of side of square = (4x - 5) inches
Step-by-step explanation:
We are given;
Area of square = 16x² – 40x + 25
Let's find the roots of this quadratic equation [-b ± √(b² - 4ac)]/2a
Thus;
x = [-(-40) ± √((-40)² - 4(16 × 25)]/(2×16)
x = [40 ± √(1600 - 1600)]/32
x = (40 ± 0)/32
x = 40/32
x = 5/4
Thus, the factors of the polynomial are;
(4x - 5)²
So,
Area = 16x² – 40x + 25 = (4x - 5)²
Since, the right hand side is (4x - 5)² and area of square is (length of side)², thus we can say that length of side of square is (4x - 5) inches
Answer:
c = 60
Step-by-step explanation:
A triangle = 180 degrees
180-(15+105)=c
c=60
