What is the area of the triangle?

Mathematics
1 answer:
docker41 [41]3 years ago
7 0

Answer:

Area = 35

Step-by-step explanation:

Triangle formula= Base x Height divided by 2.

The base is the distance between the x-axis(-4 and 6) which is 10.

The height is the y axis distance(2 and 9) which is 7.

10 x 7 = 70

70/2 = 35

What values of a and b would make the equation shown have infinitely many solutions? 3x=ax+b
Wittaler [7]
Infinitely many solutions means that you have the same thing on both sides of the equation no matter what value of x you plug in, right?

We just need both sides to be 3x then, correct?

If a were equal to 3 and b were equal to 0, we'd have

3x = (3)x + 0

Which is essentially 3x = 3x

So that means a = 3 and b = 0 must work!
Let's say x = 5

3(5) = 3(5) + 0

15 = 15 + 0

15 = 15

That means that a = 3 and b = 0 is your final answer :)

Help me pls i don't understand the problem so can u give me the answers and also explain
WARRIOR [948]

Step-by-step explanation:

1)

\frac{2}{3} +\frac{4}{5} =\frac{10+12}{15}=\frac{22}{15} .

2) the same value of the denominator of the fractions.

3) 4²*2²=16*4=64 or 4²*2²=(4*2)²=8²=64.

Megan's answer is correct.

4) if the given length is 2,25=9/4 (feet), then the length of each piece is 9/4 :3=3/4=0.75 (feet) or 3/4*12=9 (inches).

5) a. 4-6= -2; b. -4+6=2; c. -4-6= -10, so the required order is c<a<b.

6) A. -8+3= -5; B. -8*3= -24, so the greater value is (-5) - answer A.

7) if to calculate every option, then A. 2.3*6.5=14.95; B. 21.45-6.5=14.95; C. 8.32+6.63=14.95, - all of them are equal.

How do I solve questions 1,2 and 6?
Talja [164]

Answer:

<h2>1. P = 13.254</h2><h2>2. P = 6.64 + 2x</h2><h2>6. P = 10</h2>

Step-by-step explanation:

1.\\\text{The length of semicircle:}\\\\l=\dfrac{1}{2}d\pi\\\\d-diameter\\\\d=2.2\\\\\text{substitute:}\\\\l=\dfrac{1}{2}(2.2)\pi=1.1\pi\approx(1.1)(3.14)=3.454\\\\\text{The perimeter of the figure:}\\\\P=2(3.8)+2.2+3.454=13.254

2.\\P=2(3.32)+2x=6.64+2x

6.\\\text{Look at the picture.}\\\\P=4(2)+2(1)=8+2=10
