<u>angle B and angle G</u> are congruent because of the alternate exterior angles theorem.
<u>angle A and angle H</u> are also congruent, because of the same theorem.
So, the answers are <u>A, and D</u>
Answer:
10f-30g
Step-by-step explanation:
we have:
5(2f - 6g)
we apply distributive property:
5(2f - 6g)
5*2f+5*(-6g)
finally we have:
10f-30g
Answer:
Step-by-step explanation:
1) A perfect square is a whole number which is a product of a smaller whole number and itself. Examples of perfect squares are
4(2 × 2)
9(3 × 3)
16(4 × 4)
25(5 × 5)
36(6 × 6)
2) Square root of 4x² is 2x(product of square root of 4 and square root of x²)
3) square of 25 is 5
4) 4x² + 20x + 25
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 4
b = 20
c = 25
Therefore,
x = [- 20 ± √(20² - 4 × 4 × 25)]/2 × 4
x = [- 20 ± √(400 - 400)]/8
x = [- 20 ± 0]/8
x = - 20/8
x = - 2.5
Answer: 3.75 ft
Step-by-step explanation:
30/8=3.75
So since area is A= L*W
8*3.75=30 ft2
Write x-4 instead of y.
x²+(x-4)²=40
x²+x²-8x+16=40
2x²-8x-24=0
x²-4x-12=0
(x-6)(x+2)=0
x=6 or x=-2
for x=6, y=6-4 = 2
for x=-2, y=-2-4 = -6
