The first incorrect step would be step number three since when solving Absolute-Value Equations, when you isolate the Absolute-Value bars and the terms inside of it, the next step should be to make two equations: one that equals the original number given on the right side of the equal sign and one that is the opposite of the number on the equal sign. For example, in this case, Step three should have turned out more like this:

|2x - 3| = 3

2x - 3 = 3 AND 2x - 3 = -3

Step 3 is the frist incorrect step it should be: 2x-3=3 or 2x-3=-3

I NEED HELP CUZ I DONT KNOW HOW TO DO THIS

mars1129 [50]

Area of rectangle = l*w
Area of triangle = (1/2)*l*w

Based on the figure:

Area of triangles = 2*(1/2)*l*w
= 2*(1/2)*24*14 = 336 cm^2

Area of side rectangles = 2*l*w
= 2*44*25 = 2200 cm^2

Area of bottom rectangle = l*w
= 44*14 = 616 cm^2

To find the total surface area, you would add all of the sides together:

336+2200+616= 3152 cm^2

Don’t be afraid to ask any questions, if you have any :D

Answer a, b and c. See image below

dlinn [17]

Answer:

a) 3/5 < 4/5

b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.

c) $\frac{7}{10} > \frac{9}{15}$ or $\frac{7}{10}$

Step-by-step explanation:

a) 3/5 < 4/5

Flip the sign and the placement of the fraction so 3/5 is less then 4/5.

b) In general if two fractions have the same denominator, then whichever fraction has the numerator closer to its denominator will be the largest fraction.

c) We need to change the denominators to a common denominator to compare the size of the two fractions:

$\frac{7}{10}$ × $\frac{3}{3}$ = $\frac{21}{30}$

$\frac{9}{15}$ × $\frac{2}{2}$ = $\frac{18}{30}$

The common denominators of the two fractions is 30. Comparing the two fractions:

$\frac{21}{30} >\frac{18}{30}$ or $\frac{18}{30}$

so we get: $\frac{7}{10} > \frac{9}{15}$ or $\frac{7}{10}$

In triangle STU, u2 = s2 + t2. Triangle STU has sides s, t, u opposite to the corresponding vertices S, T, U Which equation is t

wlad13 [49]

Answer:
The measure of angle SUT is equal to 90 degrees

Explanation:
The Pythagorean theorem states that:
"In any right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides"
In other words:
(hypotenuse)² = (first side)² + (second side)²

Now, for the given, we have:
u² = s² + t²
This means that the given triangle UST is a right-angled triangle and that side "u" is its hypotenuse.

According to the given, the angle opposite to side "u" is angle U. This means that angle U is the right-angle in this triangle.

Based on the above:
angle U = 90°
angle S + angle T = 180 - 90 = 90°

Now, comparing our deductions to the given choices, we can conclude that the correct choice is:
The measure of angle SUT is equal to 90 degrees

Hope this helps :)
