Answer:
x = 7
Step-by-step explanation:
Similar
The two triangles
1) the one making up the peak of the large triangle
2)the large triangle
are similar. That is because the 2 bases are parallel and corresponding angles are equal. The third angle at the peak is common. So by AAA they are similar.
Proportion
Therefore the sides are in proportion.
5/40 = 3/(2x + 10)
Solution
Cross multiply
5*(2x + 10) = 40*3
Remove the brackets on the left. Combine the right.
10x + 50 = 120
Subtract 50 from both sides
10x + 50 - 50 = 120 - 50
10x = 70
Divide by 10
10x/10 = 70/10
x = 7
Answer:
2 option= 3+3+3+3= 3(4) because it do not have exponent!!
Step-by-step explanation:
Answer:
√3
√5
22/7.
16/4
Step-by-step explanation:
22/7 = 3.14
√3 = 1,73
16/4 = 4
√5 = 2.23
the least would have the smallest value. the greatest would have the largest value
Answer:
To find the x-intercept, simply plug in the value y = 0 into your equation and then solve for x. To find the y-intercept, plug in x = 0 and solve for y.
You plug in 7 for f(x) so you solve for 7=2x+3. The final answer is x=2
