Answer:
x=75
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.
42 50
------ = ----------
42+63 50+x
42 50
------ = ----------
105 50+x
Using cross products
42(50+x) = 50*(105)
2100+42x = 5250
Subtract 2100 from each side
2100-2100+42x = 5250-2100
42x =3150
Divide by 42
42x/42 = 3150/42
x = 75
Answer:
i
( the comma means there is space between the sqrt of 2 and the i.

Answer:
C
Step-by-step explanation:
x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3)
or delta:
∆=2²-4*1*(-15)=4+60=64
√∆=8
x1 = (-2+8)/2 = 3
x2=(-2-8)/2=-5
and 4x+20 = 4(x+5)
The same is (x+5), so it is GCF. answer C
Systemic chemotherapy's impact on survival and recurrence in people with high-grade glioma has not been conclusively studied.
<h3>What is Systemic chemotherapy?</h3>
Patients undergoing systemic chemotherapy can get their chemotherapy drugs intravenously or orally. The medication may be injected into the body intravenously, or through an IV, or intramuscular, into a muscle (IM).
Some Key features of systemic chemotherapy are-
- Background: In order to evaluate the effects of such treatment on survival and recurrence, we conducted a systematic review and meta-analysis.
- Methods: From 12 randomised controlled studies, information on 3004 patients was incorporated (11 published and one unpublished).
- Findings: Overall, the findings indicated a significant survival extension associated with chemotherapy, with a hazard ratio of 0.85 (95 percent confidence interval [CI] 0.78–0.91, p0.0001) or a relative reduction in mortality risk of 15%. There was no proof that a patient's age, gender, histology, performance status, or degree of resection affected how chemotherapy worked in any particular way.
- Interpretation: Further research into pharmacological treatment for malignant tumors is encouraged by this modest but noticeable improvement in survival from chemotherapy.

Answer: Estimate: 36 ? units ? miles per hour ? feet per second?
Exact: 35.32142857 but if you are supposed to use significant digits, 35.32 is probably good.
Step-by-step explanation: For the estimate, round off the fractions to whole numbers, so multiply 6 x 6 to get 36
For exact I converted the mixed numbers to improper fractions, 5 3/4 = 23/4 and 6 1/7 = 43/7. Then multiplied the numerators 23 x 43= 989. And denominators, 4x7=28.
Divide numerator by denominator 989/28= 35.321428571
