No
Step-by-step explanation:
For a triangle to have a right angle the square sums of the legs have to equal the square of the hypotenuse.
In this case 9 is the hypotenuse which is the longest side in a triangle. 5 and 7 are the two smaller sides which make them the legs.
Putting this set of numbers into the pythagorean theorem is the way to solve this.
5²+7² should equal 9² if the triangle is a right triangle.
Solve the squares: 25+49=81
This would add up to be 74 and that is not equal to 81, so by this statement we can conclude that 5, 7, and 9 do not make a right triangle.
Answer: x = 4.69/ x = (squareroot) 22
<h2>Steps</h2>
Quadratic Equation: 17 - x² = -5
Subtract 17 from both sides
17 - x² - 17 = -5 - 17
Simplify
-x² = -22
Divide both sides by -1
-x² / -1 = -22 / -1
Simplify
x² = 22
x = (squareroot) 22 or
x = 4.69
Answer:
1(a)1,030,000+0.13x
(b)$1,030,026
2. (a)Base and Index
(b)See Explanation
Ste-by-Step Explanation
(a)Total Amount to be paid to the four actors
=500,000+(300,000+0.02x)+(150,000+0.03x)+(80,000+0.08x)
Collect like terms
=500,000+300,000+150,000+80,000+0.02x+0.03x+0.08x
(b)When x=200
<u>Question 2</u>
(a)The two parts of a power are the base and index.
Take, for example, the expression: 
Another example using numbers is: 
In this case:
(b)Like terms are terms that have the same letter/variable attached to them.
For example, the following pairs are like terms
- 8x and 3x
- 4y and -9y
- 6pq and pq
- 3 and 3
These, however, are not like terms
Answer:
Step-by-step explanation:
right angle: an angle of 90°
vertical angles: each of the pairs of opposite angles made by two intersecting lines.
complementary angles: either of two angles whose sum is 90°.
Step-by-step explanation:
3 pairs of flip flops = 14.95 x 3 = 44.85
Total amount spent = 44.85 + 21.50 + 9.99 + 15. 44 = 91.78
After adding tax = 91.78 + 7.34 = 99.12
Mrs B spent 99.12 altogether
Budget = 100
Then money left = 100 - 99.12 = 0.88
